Review on 🌡️ Gowoops 2pcs DHT22/AM2302 Arduino Raspberry Pi Digital Humidity Temperature Sensor Module, DIY Temp Humidity Gauge Monitor for Electronic Projects, SHT11 SHT15 Replacement by Matt Davis

They are as accurate as any other thermometer and hygrometer I have at home. I connected them to several Raspberry Pi Zeros and installed them in several rooms in my house where the temperature fluctuates wildly so I can remotely monitor the temperature on my phone. I've created a website that shows readings from these sensors and sends me text alerts when the temperature or humidity is out of range. They simply connect to the GPIO pins on your Raspberry Pi and come with all the necessary cables. to hook them up, and the sample code for working on Arduino or Pi provided in the product description is a good starting point for using them in your own projects.
