The NODE is a rather clever device. It’s a multi-function remote sensor, that links via Bluetooth with a paired smartphone. Different sensing modules can be swapped on and off of the main NODE ...

Can you buy a working radar module for $12? As it turns out, you can. But can you make it output useful information? According to [Mathieu], the answer is also yes, but only if you ignore the datas… ...

What's a modular sensor without modules? The folks behind Node have released the iPhone peripheral's fifth end cap, the NODE+chroma, a sensor that scans colors, transmitting that data to your ...

One of the biggest challenges for wireless sensor networks is that of power. Solar panels usually produce less power than you hoped, especially small ones, and designing super low power circuits is… ...

A simple node.js module for reading temperature and relative humidity using a compatible DHT sensor.

Due to their miniaturization, sensor nodes cannot compete with computers, smartphones, tablets for example, especially in terms of data processing, storage, and communication capacity. The hardware ...

This Sensor Node project, which uses low-energy and long-range LoRa data transmission, can be used for remote environmental monitoring. Utilizing the LoRa WIO E5 Module and an ESP32-C3 XIAO controller ...

SQLite in Node makes it easier than ever to persist data with server-side JavaScript. Get started with the node:sqlite module.
