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.

This kit includes dual 5mm thick acrylic sheets with four high torque encoder gear motors and mecanum wheels. The chassis provides enough space to add sensors like LiDAR or camera for computer vision, as well as a computer like Raspberry Pi or Nvidia Jetson or an Arduino MCU and batteries. Mecanum wheels are very useful to increase the maneuverability of a robot. These wheels come with 45º rollers that move independently and allows the robot to move forward, backward, sideways, diagonally or spin in place. But please, don’t make the confusion with omnidirectional wheels. Mecanum wheels are different than omnidirectional wheels, but the result is almost the same. Depending on which wheels rotate in which direction, the robot will change the heading or spin in place. The motors have attached encoders. Having encoders, you can add an IMU sensor and create a map of the room. This makes it easier to transform this chassis into an autonomous robot, that is able to navigate on smooth surfaces in an apartment, building or factory floor. Mecanum wheels have some disadvantages compared with the “normal” wheels that we’re using for our cars or shopping carts. These wheels tend to wander side-to-side when the robot is trying to negotiate an inclined floor. Also, mecanum wheels are known for losing traction.   Motor Parameters: Model: GB37-520 Speed: 330RPM Rated current: ≤0.7A Rated voltage: DC12V Rated power: ≈ 7.2W Length L: 58mm Diameter R: 37mm Maximum encoder accuracy: 1320CPR
