Using any Raspberry PI and a DHT11, DHT22 or DHT2302 sensor, read and publish data to an MQTT broker. The DHT11 is a low-cost and popular sensor for measuring temperature and humidity.

Raspberry Pi Humidity Temperature Sensor About The Project This project uses the SHT-31 from Adafruit connected to a raspberry pi 3 to record the temperature and relative humidty and then sends that ...

Seeking data on how well the appliance works, [Matthias] wired a DHT22 temperature/humidity sensor to a spare Raspberry Pi to monitor room conditions, and plugged the dehumidifier into a Kill-A ...

The Pi can sink up to 16mA per pin if configured properly. Try that and see what happens. I normally order a few of each sensor so I can try with a different sensor if something is acting up, though.

Raspberry Pi Pico Sense HAT monitors temp, air-quality, humidity and more 12:50 pm November 11, 2021 By Julian Horsey ...

Michael Horne’s innovative DIY project is a portable, battery-powered temperature, humidity, and pressure sensor using a Raspberry Pi Pico W.

To complete this project, we will first need a Raspberry Pi 4 along with a temperature and humidity sensor. We will be using a DHT-22 for our temperature and humidity sensor. We will then use a heated ...

Abstract: Temperature and humidity information is an important quality index of communication system. A temperature and humidity sensor network is constructed based on Raspberry Pi development ...
