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.

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

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, ...

If, for whatever reason, this sounds like something you’d find useful, the Cmicro basic set with sensor, cover, and display is on presale now for $69, the Cmicro baby set for $74, and the Cmicro ...

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 ...

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 — ...

Part of the PREMISS project, Gao's sensor is very much in the lightweight category at 2 sq mm and weighing in at 1.6 mg.
