Wireless sensor network is composed of many wireless sensor nodes with the same or different functions. A typical sensor node consists of four parts: sensor unit, information processing unit, wireless ...

In this paper, we develop an IoT node with an organic pressure sensor for structural health monitoring (SHM) system. A 100um-thick polyurethane film was sandwiched by top/bottom electrodes to complete ...

This project is a solar-powered LoRaWAN sensor node designed to monitor environmental conditions such as soil moisture, temperature, humidity, and CO2 levels. The node transmits data via LoRaWAN to ...

The main components of the sensor node is an ATMega 328P microcontroller running at 4Mhz, RFM69 radio transceiver, I2C temperature/humidity sensor, 1F supercapacitor, and a small solar panel.

A wireless sensor network used to monitor stress on a large structure. Asad Khan But … At present there are two main issues with WSNs. 1) The energy needs of individual sensors have to be met ...

An IoT gateway and a series of wireless sensor nodes have been announced by Portwell. The IoT gateway, XM-1, is said to be the first to feature international patents of highly composable structure.
