THRESHOLD is the maximum temperature we wish to maintain. When the temperature rises too high, a fan is switched on. A small HYSTERESIS value is used to prevent the fan rapidly switching when the ...

A simple ESP32-based program to scan and display the addresses of DS18B20 temperature sensors connected to a 1-Wire bus. This program helps identify all sensors on the bus, validate their addresses ...

The block diagram of this simple project is shown in Fig. 1 and its circuit diagram is in Fig. 2. The project is built around water temperature sensor probe DS18B20, a 4-digit multiplex 7-segment ...

First of all, there are definitely simpler ways to monitor remote temperatures, but [Mike]’s remote MQTT temperature sensor and display project is useful in a few ways. Not only does it lay o… ...

Temperature Analysis Including Headcount is intended to analyze the temperature and headcount of everyone within the sensor's range. In this project, 37°C is used as a base temperature. A person whose ...

It comes with a built-in DHT22/AM2302 temperature and humidity sensor and has slots for a mini OLED display, waterproof DS18B20 temperature sensor, and empty slots for up to three additional I2C ...
