Thyristor used as a temperature sensor and switch This circuit detects if the temperature of an object became too high. The thyristor is mounted on the object that has to be temperature monitored. If ...

Circuit and working Circuit diagram of the temperature controlled switch is shown in Fig. 2. The circuit comprises step-down transformer X1, bridge rectifier BR1, 5V voltage regulator 7805 (IC1), ...

This project demonstrates how to build a temperature and humidity sensor using the DHT22 sensor and the ESP8266 (Wemos D1 Mini) board, perfect for integrating into your Home Assistant setup. The ...

This project shows how to build a liquid level switch by using an IR liquid level sensor. An IR liquid level sensor works similar to an IR light barrier, with a transparent plastic cover. When the ...

In this project tutorial we build a Temperature Gun using Arduino and an Infrared Temperature Sensor. This Thermal gun will be built using a non-contact temperature sensor called MLX90614; ...

This circuit will serve as automatic light switch which will trigger if temperature goes beyond a particular level (50 Degree in this circuit). We are using LM35 as temperature sensor here. This ...

The DHT11 sensor is a good value temperature & humidity sensor giving a ±2ºC temperature accuracy and a ±5%RH humidity accuracy. It is one of the most common sensors used in Smart Devices.
