The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

There’s an Arduino with a custom shield that interfaces the barometric pressure sensor, real-time clock chip, a digital temperature sensor, and a humidity sensor.

For this project, you will need a DHT sensor to detect the temperature/humidity, Arduino microcontroller, and a WiFi module. Using these guidelines, you can easily learn how to build this device ...

Made by Renesas, the single-channel, non-dispersive infra-red module is called RRH47000 and has automatic baseline calibration for measurement from 0 to 5,000ppm. Also in there are temperature and ...
