Sense Node C3

Sense Node C3 is a sensor node base for your smart home. You can solder on different sensors on it to create your own custom node. With the little proto area, you can easily create your own custom node. Like a PIR sensor with photoresistor to light up a night light at night.

It’s make for Home Assistant with ESPHome, but compatible for almost all other IoT Platform like Blynk, AWS IoT, Azure IoT, etc. Or even your own simple IoT Platform.
