The project is completely open source and based on a Raspberry Pi base station which connects to ESP32 based sensor nodes and online services to nicely present the data on a 7″ touch screen display.

By minimizing the number of sensors nodes in the network, the WSN would be less costly to install and maintain. Wireless sensor nodes have limited detection and connectivity ranges; therefore ...

The HS-Link high-speed wireless node has 100-kHz sample rates on its ... the data transfers to nonvolatile Flash memory. Each sensor channel has a dedicated 16-bit a/d converter which lets the ...

Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so well ...

A wireless sensor node by Germany-based Micropelt is powered by harvesting thermoelectric energy. When a product derives its power from batteries, the user is saddled with the inconvenience of ...

Can you imagine a world where millions of interconnected wireless sensors ... These sensor readings are processed by a tiny on-board computer, known as a node, which wirelessly communicate the ...

Two new products extend the communication and measurement capabilities of the National Instruments wireless sensor network (WSN) platform. The NI 9792 is a programmable WSN gateway that can ...
