Parametric Motion / Light Sensor

thingiverse

Motion and Light Sensor for MySensors with Arduino Nano, HC-SR501, and NRF24L01. The light sensor is a basic voltage divider consisting of an LDR and a 10k resistor. The LDR is connected between GND and A0, while the resistor is connected between +5V and A0. All electronic components were purchased on AliExpress (links are examples). - Arduino: [Freeshipping 10PCS LOT Nano 3.0 Controller Compatible with Arduino Nano NO CABLE](https://de.aliexpress.com/item/Freeshipping-10PCS-LOT-Nano-3-0-controller-compatible-with-arduino-nano-NO-CABLE/1950565375.html) - NRF24L01: [10PCS NEW NRF24L01 2.4GHz Antenna Wireless Transceiver Module](https://de.aliexpress.com/item/10PCS-NEW-NRF24L01-2-4GHz-Antenna-Wireless-Transceiver-Module/32216845738.html) - HC-SR501: [10PCS HC-SR501 Adjust IR Pyroelectric Infrared PIR Motion Sensor Detector Module](https://de.aliexpress.com/item/10PCS-HC-SR501-Adjust-IR-Pyroelectric-Infrared-PIR-Motion-Sensor-Detector-Module/32294032548.html) - MicroUSB Breakout Board: [10-st cke Breakout Netzteil DIY Elektronische PCB Board Modul Power Adapter Board USB Breakout Modul](https://de.aliexpress.com/item/10-st-cke-Breakout-Netzteil-Diy-Elektronische-PCB-Board-Modul-Power-Adapter-Board-USB-Breakout-Modul/32886102706.html) - 3.3V Voltage Regulator: [5PCS 5V 3.3V DC DC Step Down Power Supply Buck Module AMS1117 LDO 800MA](https://de.aliexpress.com/item/5PCS-5V-3-3V-DC-DC-Step-Down-Power-Supply-Buck-Module-AMS1117-LDO-800MA/32732025305.html) - LDR: [50-ST cke LDR Foto Light Sensitive Resistor Photoelektrische Fotowiderstand 5528 GL5528](https://de.aliexpress.com/item/50-ST-CKE-LDR-Foto-Light-Sensitive-Resistor-Photoelektrische-Fotowiderstand-5528-GL5528/32668713683.html)
