The LX1972 is a low cost silicon light sensor with spectral response that closely emulates the human eye. Patented circuitry produces peak spectral response at 520nm, with IR response less than ±5%, of the peak response, above 900nm.
The photo sensor is a PIN diode array with a linear, accurate, and very repeatable current transfer function.
High gain current mirrors on the chip multiply the PIN diode photo-current to a sensitivity level that can be voltage scaled with a standard value external resistor. Output current from this simple to use two-pin device can be used directly or converted to a voltage by placing it in series with a single resistor at either of its two pins.
Dynamic range is determined by the resistors (typically in the range of 10K to 100K) and power supply values. Typically the LX1972 needs only 1.8V of headroom to operate at 1000 Lux illumination.
Internal temperature compensation allows dark current to be kept below 200nA over the full specification.
Temperature range (-40 to +85°C), providing high accuracy at low light levels. Usable ambient light conditions range is from 1 to more than 5000 Lux.
The LX1972 is optimized for controlling back lighting systems in low cost consumer products such as LCD TV, portable computers, and digital cameras.

The long awaited BME680 from Bosch gives you all the environmental sensing you want in one small package. This little sensor contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities. All over SPI or I2C at a great price!
Like the BME280 & BMP280, this precision sensor from Bosch can measure humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter or better accuracy!
The BME680 takes those sensors to the next step in that it contains a small MOX sensor. The heated metal oxide changes resistance based on the volatile organic compounds (VOC) in the air, so it can be used to detect gasses & alcohols such as Ethanol, Alcohol and Carbon Monoxide, and perform air quality measurements. Note it will give you one resistance value, with overall VOC content, but it cannot differentiate gasses or alcohols.
Please note this sensor, like all VOC/gas sensors, has variability and to get precise measurements you will want to calibrate it against known sources! That said, for general environmental sensors, it will give you a good idea of trends and comparisons. We recommend that you run this sensor for 48 hours when you first receive it to "burn it in", and then 30 minutes in the desired mode every time the sensor is in use. This is because the sensitivity levels of the sensor will change during early use, and the resistance will slowly rise over time as the MOX warms up to its baseline reading.
For your convenience we've pick-and-placed the sensor on a PCB with a 3.3V regulator and some level shifting, so it can be easily used with your favorite 3.3V or 5V microcontroller.

Metal alloy mechanical arm with 6 Degree Of Freedom. The kit is delivered in a simple carton. The subassemblies are packaged in separate bags. The structural elements of the robotic arm are made by stamping aluminum plate. To give a better appearance and deburr the edges, the pieces are sandblasted. Black anodising (visible on the assembly instructions) has been abandoned. Positive point of this kit, we find very easily spare parts. Most structural elements, servo motors MG996R, flanged base, clamp (or claw) are standard elements that are found very often our store.
