If you want to get started with motion sensors and the like, ESPHome makes it incredibly easy to build your own sensors.

In testing, his chip started out at 20°C and reached equilibrium at 24°C after about a minute. Pretty neat, and could be used as a temperature sensor for a project in a pinch.

The device uses a PCB that integrates an ESP32-C3-mini with the CO₂ Sensor (SCD40). The PCB also has connectors for the ...

[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a temper… ...

The project presented here is a starter one that monitors and displays two prominent environmental parameters: air pressure and air temperature. At the heart of the project is a GY-BM E/P 280 module — ...

Within the project, the students selected and attached a wireless thermosensor to a red snapper turtle. Given the client’s preferences, the ThermoWorks RG ThermaData Temperature Logger was selected, ...

TU/e researcher Hao Gao as developed a tiny transmitting temperature sensor that is powered by radio waves, eliminating the need for wires or batteries. Instead, it picks up radio waves from a ...

A new Indiegogo campaign has appeared to help you monitor your food’s temperature when you microwave it. Called Cmicro, the device consists of a little puck (the actual sensor), a number of ...

This project is to prototype a set of self-powered (such as piezoelectric, thermostat, solar, etc) embedded sensor systems for pervasive computing. A tangible exam is a body-temperature powered motion ...
