Presented here is a humidity and temperature monitoring using Arduino. In this article, humidity and temperature information from DHT-11 sensor is analysed graphically on ThingSpeak platform using ...

A temperature and humidity logger using a ESP8266 in conjunction with a Si7021 i2c temperature and humidity sensor. The ESP8266 will also act as a HTTP server and will return a response in json ...

Circuit diagram. The circuit diagram of the IoT-based data logger is shown in Fig. 5. Fig. 5: Circuit diagram of the data logger. It consists of DHT22 sensor, WeMos D1 R1 board, OLED display and 3.7V ...

This project provides an ESP8266-based solution for monitoring temperature and humidity with a real-time display on an OLED screen. It also includes a low battery warning feature. Measures temperature ...

We previously used NodeMCU to log temperature data in the Google sheet.Now here we are going to send data to Thinger.io IoT cloud and display it in an attractive graphical format. A BMP180 sensor is ...
