Arduino Board: Serves as the central control unit to process sensor data. DHT11 Sensor: A compact and affordable sensor for measuring temperature (in Celsius) and humidity (as a percentage).

Connect Gnd pin of DHT11 module to Gnd(pin 6) of Raspberry pi Connect Signal pin of DHT11 module to GPIO 4(pin 7) of Raspberry pi To run type -> node main.js ...

The sensor checks temperature and humidity in real-time using Wi-Fi. It is simple to set up and works well in homes, farms, and offices. Numato Lab’s SenzConnect RHT module is an IoT device that lets ...

In addition to the ESP-7 or 12 module ... It’s a simple enough idea, and with an Arduino and a DHT11 temperature and humidity sensor, it was pretty easy to put together.

Abstract: The traditional cable data transmission is high cost and big interference. instead, the wireless data transmission has advantages like: low cost, better applicability and lower interference.

The core architecture of the system designed in this paper is based on STM32 micro-controller, integrated with DHT11 temperature and humidity sensor, BH1750 light intensity detector and other ...
