Xadow - Basic Sensors
Xadow Basic Sensors integrates three different sensors on one single board:
- 3-Axis Accelerometer for motion detection, activity monitoring and speed tracking
- Dual diode Digital Light Sensor that can separately measure infrared, full-spectrum or human-visible light
- Temperature Sensor for temperature monitoring.
Features
- Three-in-one sensor board
- Plug-and-play if connected with RePhone Kit Create
- Open source and modular design
- Slim and small
- Built-in 11 PIN Xadow Connectors for fully flexible connection with other Xadow Modules
- Stackable, chain-able and sew-able with other Xadow Modules.

Hardware Overview
Use it with RePhone Kit Create
Obtain the Sensor Data
Without any programming, you can connect it to the Core Module (Xadow GSM+BLE) of your ‘RePhone Kit Create' to read all the data from the sensors.
Set 'If This Then That
You can also set the sensor data as a condition to trigger a series of actuators like audio, LED matrix and LED strip, or trigger actions like making a call and sending a message.
RePhone Community
We’ve been looking for a better place where our backers (RePhone Users) can sit together, warmly and comfortably, have conversations about RePhone, discuss technical problems, share ideas/projects, and give feedback on the modules’ development in the future. And then here we go, the RePhone Community.
Now join us in the RePhone Community! Together we seek answers, make interesting stuff, care about each other, and share our experiences.
Frequently Asked Questions
Some frequently asked questions in RePhone Community are collected and answered to the topic "Frequently Asked Questions of RePhone (FAQ)" , the topic will be kept updating whenever a new FAQ comes out.
