We've seriously overhauled the PCB design on the back of the screen by including an ATMega328P that handles all of the screen control
This MicroPressure Sensor offers a calibrated and compensated pressure sensing range of 60mbar to 2
Integrated watchdog function
3522 - Sharp Distance Sensor GP2Y0A02YK0F (20-150cm)
data collection functions can be performed easily using the 2G GSM/GPRS based cellular network
Gravity: MEMS Gas Sensor (CO, Alcohol, NO2 & NH3) - I2C - MiCS-4514 SF_Development Kits We've seriously overhauled the PCBThis is a 3. 3 5V compatible MEMS gas concentration sensor from DFRobot. This sensor supports the detection of various gas concentrations like CO, C2H5OH (Alcohol), H2, NO2, NH3, and integrates various gas concentration conversion formulas in the code to facilitate the testing and use of sensors. With I2C output and 3. 3~5. 5V wide voltage input , it is compatible with Arduino , ESP32 , Raspberry Pi and other mainstream controllers. Board Overview
