DHT11 / DHT22 Library for Proteus V1.0: Temperature Humidity Sensor

DHT11 / DHT22 Library for Proteus V1.0: a DHT11 module with its STATUS panel and the Advance pop-up of a DHT22 at -18 C

Hello friends, I hope you all are doing great. Today, I am going to share the new DHT11 / DHT22 Library for Proteus V1.0 . The DHT11 and the DHT22 are the temperature and humidity sensors of almost every first weather station, greenhouse, incubator and smart home project. They are cheap, they need only one data wire, and the Adafruit library reads them in two lines of code. Now you can build and test them in Proteus, on the small 3-pin modules most of us buy. Behind the parts sits our own model , not a part that shows a number. It speaks the sensors' real single-wire protocol : it waits for the Arduino's start signal, measures how long DATA was held LOW, answers with LOW and HIGH pulses and sends 40 bits , each timed like the datasheet's, with the checksum. It also behaves like the real se ...
