Platinum (PT100) RTD Temperature Sensor Amplifier - MAX31865 from ₹ 259.99 ₹ 599.00
The MAX31865 is an easy-to-use resistance-to-digital converter optimized for platinum resistance temperature detectors (RTDs). An external resistor sets the sensitivity for the RTD being used and a precision delta-sigma ADC converts the ratio of the RTD resistance to the reference resistance into digital form. The MAX31865's inputs are protected against overvoltage faults as large as ±45V.  For precision temperature sensing, nothing beats a Platinum RTD. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor. In this sensor, the resistor is actually a small strip of Platinum with a resistance of 100 ohms at 0°C, thus the name PT100 The MAX31865 handles all of your RTD needs, and can even compensate 3 or 4 wire RTDs for better accuracy. Connect to it with any microcontroller over SPI and read out the resistance ratio from the internal ADC. A 430Ω 0.1% resistor as a reference resistor on the breakout is used. We even made the breakout 5V compliant, with a 3.3V regulator and level shifting, so you can use it with any for For Arduino or microcontroller.

VL53L0X Laser Ranging Sensor Time-of-Flight (ToF) - VL53L0X Laser Ranging Sensor Time-of-Flight (ToF) -
GY-53 VL53L0X Time-of-Flight Module ₹ 439.99 ₹ 965.00
The VL53L0X from ST Microelectronics is a time-of-flight ranging system integrated into a compact module.  The VL53L0 uses ST's FlightSense technology to precisely measure how long it takes for emitted pulses of infrared laser light to reach the nearest object and be reflected back to a detector, so it can be considered a tiny, self-contained lidar system. This time-of-flight (TOF) measurement enables it to accurately determine the absolute distance to a target without the object's reflectance greatly influencing the measurement. The sensor can report distances of up to 2 m (6.6 ft) with 1 mm resolution, but its effective range and accuracy (noise) depend heavily on ambient conditions and target characteristics like reflectance and size, as well as the sensor configuration. (The sensor's accuracy is specified to range from ±3% at best to over ±10% in less optimal conditions.) Ranging measurements are available through the sensor's I2C (TWI) interface, which is also used to configure sensor settings, and the sensor provides two additional pins: a shutdown input and an interrupt output.The VL53L0X is a great IC, but its small, lead less, LGA package makes it difficult for the typical student or hobbyist to use. It also operates at a recommended voltage of 2.8 V, which can make interfacing difficult for micro controllers operating at 3.3 V or 5 V. Our breakout board addresses these issues, making it easier to get started using the sensor, while keeping the overall size as small as possible Fully integrated miniature module – 940 nm laser VCSEL – VCSEL driver – Ranging sensor with advanced embedded micro controller – 4.4 x 2.4 x 1.0 mm Fast, accurate distance ranging – Measures absolute range up to 2 m – Reported range is independent of the target reflectance – Advanced embedded optical cross-talk compensation to simplify cover glass selection Eye safe – Class 1 laser device compliant with latest standard IEC 60825-1:2014 - 3rd edition Easy integration – Single reflowable component – No additional optics – Single power supply – I2C interface for device control and data transfer – Xshutdown (reset) and interrupt GPIO – Programmable I2C address Specifications  Resources Datasheet Libraries Sample Code Tutorials

Electret Microphone Amplifier - MAX4466 with Adjustable Gain - Electret Microphone Amplifier - MAX4466 with Adjustable Gain -
Electret Microphone Amplifier - MAX4466 Sound Sensor with Adjustable Gain ₹ 249.99 ₹ 290.00
This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent power supply noise rejection, so this amplifier sounds really good. This breakout is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT. A small trimmer pot to adjust the gain, lets you set the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6" away) which is good for attaching to something that expects 'line level' input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC. Using it is simple: connect GND to ground, VCC to 2.4-5VDC. For the best performance, use the "quietest" supply available (on an Arduino, this would be the 3.3V supply). The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). If the audio equipment you're using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required. +2.4V to +5.5V Supply Voltage Operation Versions with 5nA Complete Shutdown Available Excellent Power-Supply Rejection Ratio: 112dB Excellent Common-Mode Rejection Ratio: 126dB High AVOL: 125dB (RL = 100kΩ) Rail-to-Rail Outputs Low 24µA Quiescent Supply Current Specifications Resources DatasheetSample Code Tutorials

BNO055 9-DOF Absolute Orientation Sensor - BNO055 9-DOF Absolute Orientation Sensor -
BNO055 9-DOF Absolute Orientation Sensor ₹ 3,695.99 ₹ 4,299.00
The BNO055 is the first in a new family of Application Specific Sensor Nodes (ASSN) implementing an intelligent 9-axis Absolute Orientation Sensor, which includes sensors and sensor fusion in a single package. The task of turning the sensor data from an accelerometer, gyroscope and magnetometer into actual "3D space orientation" can be daunting! Orientation is a hard problem to solve. The sensor fusion algorithms (the secret sauce that blends accelerometer, magnetometer and gyroscope data into stable three-axis orientation output) can be mind-numbingly difficult to get right and implement on low cost real time systems. Bosch is the first company to get this right by taking a MEMS accelerometer, magnetometer and gyroscope and putting them on a single die with a high speed ARM Cortex-M0 based processor to digest all the sensor data, abstract the sensor fusion and real time requirements away, and spit out data you can use in quaternions, Euler angles or vectors. NOTE: Don't forget to solder the jumpers S0 and S1 to turn on I2C or UART modes of communication. Connecting S0 and S1 to ground will turn on I2C.   The BNO055 can output the following sensor data: Absolute Orientation (Euler Vector, 100Hz) Three axis orientation data based on a 360° sphere Absolute Orientation (Quaterion, 100Hz) Four point quaternion output for more accurate data manipulation Angular Velocity Vector (100Hz) Three axis of 'rotation speed' in rad/s Acceleration Vector (100Hz) Three axis of acceleration (gravity + linear motion) in m/s^2 Magnetic Field Strength Vector (20Hz) Three axis of magnetic field sensing in micro Tesla (uT) Linear Acceleration Vector (100Hz) Three axis of linear acceleration data (acceleration minus gravity) in m/s^2 Gravity Vector (100Hz) Three axis of gravitational acceleration (minus any movement) in m/s^2 Temperature (1Hz) Ambient temperature in degrees Celsius Specifications  Resources Datasheets Libraries  Sample Code Tutorials

The moisture sensor probes are coated with immersion gold that protects Nickel from oxidation. These two probes are used to pass the current through the soil and then the sensor reads the resistance to get the moisture values.   Preset (Trimmer pot) Using the onboard preset you can adjust the threshold (sensitivity) of the digital output.   How to Use Soil Moisture Sensor Module Moisture sensor module consists of four pins i.e. VCC, GND, DO, AO. Digital out pin is connected to the output pin of LM393 comparator IC while the analog pin is connected to Moisture sensor. The internal Circuit diagram of the Moisture sensor module is given below. Using a Moisture sensor module with a microcontroller is very easy. Connect the Analog/Digital Output pin of the module to the Analog/Digital pin of Microcontroller. Connect VCC and GND pins to 5V and GND pins of Microcontroller. After that insert the probe inside the soil. When there is more water presented in the soil, it will conduct more electricity that means resistance will be low and the moisture level will be high.   Applications of Soil Moisture Sensor Gardening Irrigation Systems Used in Controlled Environments
