E.g. DHT22 gets power, ground and resistor is connected correctly. If all above are right, try to connect your sensor to another GPIO and see if you get reading from that ...

– DHT22 — This temperature and humidity sensor has temperature accuracy of +/- 0.5 C and a humidity range from 0 to 100 percent. It is simple to wire up to the Raspberry Pi and doesn’t ...

Those interested in building a Raspberry Pi-based temperature monitor can reference a Hackster.io project which uses a Raspberry Pi 3 Model B mini PC and various temperature sensors and the Initial ...

The project is completely open source and based on a Raspberry Pi base station which connects to ESP32 based sensor nodes and online services to nicely present the data on a 7″ touch screen display.

As you’d expect, you’ll need a couple of Raspberry Pis, a touch screen, a temperature sensor, a Raspberry Pi camera, and a pair of Wi-Fi dongles.

To build your very own IoT rain checking system, you will need a Raspberry Pi 3 Model B, a DHT11 Temperature & Humidity Sensor (4 pins), and a raindrop sensing board, which can be purchased for ...
