How to detect object's fall out

Showcase, May 20, 2016 - 3:08pm, 2869 views

Depending on project there may be a need to detect fall out of an object. There are several ways to do this. One is to use a tilt sensor. Here we show how easy it is to integrate one with the Concept Board. 
Tilt sensor
Hardware remarks:
- We used 45 degrees double angle tilt sensor (
- The switch is triggered when tilted 45 degrees of the horizontal position.
- Sensor has three lines, they need to be connected to GND, 5V and GPIOx (we have used GPIO5)
- If using GPIO5 application ***** to make sure that GPIO5 is not used by SYNC LED on the module. To check this use <"AT^SCFG="Gpio/****/SYNC"> command. If it's value will be other that "gpio" send: AT^SCFG="Gpio/****/SYNC","gpio". NOTE: module ***** to be rebooted after sending this command, so changes can take effect.
