This is a simple project using Raspberry pi which uses the following components: 1. Raspberry pi 2. DHT-11 Temperature Humidity Sensor
I have connected 3 DHT-11 sensors simultaneously on pins 4, 13 and 16 respectively and have also provided a usecase of how to initialize the class object and execute all the three simultaneously.
This could be used as a homemade fire-alarm and can also be mapped with sprinklers and many more applications.
