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 ...

Code for the DHT22 or DHT11 humidity and temperature sensor. - pimylifeup/Arduino_Humidity_Sensor ...

The HTU21D is a digital humidity sensor with temperature output by MEAS.This sensor provides calibrated, linearized signals in digital, I2C format. HTU21D digital humidity sensors are dedicated ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...

Makers, hobbyists and electronic enthusiasts looking for a project to keep them busy this weekend may be interested in this awesome Arduino temperature and humidity sensor which has been created ...

I can check that annually and probably be fine. Soil moisture, though, is something that requires more active control. My long term goal is to integrate the sensors and some control relays for ...

As such, I'd like to build myself some wireless moisture sensors for moderate scale production (consider 50 test points reasonable).
