OK thanks again for the great software... just a thought on esp32 version.. i only just realised that the esp32 has an internal hall effect sensor... tried this code and it works great... could this ...

Would you believe it, the ESP32 popular Wi-Fi and Bluetooth chip has a built-in Hall effect sensor. Espressif Systems makes the chip, and its ESP32 data sheet has nearly no mention of the Hall sensor ...

For smart home deployments, there are a lot of ways to track the presence of individuals in a room. There are motion detection sensors that use mmWave and PIR, and you can also use simple detection ...

We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that ...

I've been playing around with a couple of ESP32 microcontrollers, and that experimentation has taught me a lot about sensors and what you can build for really, really cheap. For as little as $4, you ...

The ESP8266 and its heavyweight sibling the ESP32 are fantastic boards to develop with as they allow you to quickly and easily get a project online. Just tack a few sensors and some LEDs on them, and ...

This project runs on an ESP32 using the ESP-IDF framework. It reads 4 digital inputs and 2 analog values (ADC), and publishes the data every 2 seconds to individual MQTT topics in plain JSON format.

Abstract: Fire detectors and monitoring systems have been proven to save many lives, making them a promising investment. A fire detector is well acknowledged as one of the best preventive measures to ...
