End Device (Sensor Node) solutions for the Internet of Things (IoT).
With modularized design on its wireless connectivity and sensor module, DS1-B is equipped with multiple functions which makes the sensor node more flexible.  In order to challenge the lowest computing, DS1-B is Portwell's own-designed Arduino motherboard using a Pan Network socket which can apply to different wireless module, Wi-FI, BLE or LoRa, and different types of sensor modules, ranging from analog to digital, 3V to 5V voltage. The node can support AC, solar panel or lithium battery for power supply.
