Building this project to alert me when my kid leaves the main door unsupervised. If I connect an IR obstacle sensor module with a relay breakout board and let the relay to switch on the alarm circuit, it should work (theoretically).
Using following component:
IR sensor: http://www.bdspeedytek.com/product/fc-51-ir-infrared-obstacle-avoidance/
Relay board: https://www.techshopbd.com/product-...lay-breakout-board-single-techshop-bangladesh
My problem is the second IR sensor on top. The "IR Obstacle Sensor Module 1" in the picture should reset the alarm. But, struggling to connect it to the system.
