The $50 sensor runs on two coin cell batteries so you don’t need a nearby power source for installation.

In this video, I’m building a LoRaWAN Class A sensor node using an ESP8266, BME680 environmental sensor, and REYAX RYLR993 LoRa module. The device measures temperature, humidity, pressure, and gas ...

If you think smart home, you might not imagine a temperature sensor, but there's a lot you can achieve with one of those and ...

A dual resonator graphene sensor measures pressure with exceptional precision and stability, using built-in temperature ...

This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

The best smart thermostats we've tested can control your home's heating and cooling with your phone or voice—and might help you save on energy costs. I’ve been working with computers for ages, ...
