Features :Circuit Rating: 35V (DC)
The reason for that is that we are looking to detect motion (change) not average IR levels
5V Operation
The etching technique is a technique for selectively etching or stripping the surface of the semiconductor substrate or the surface covering film in accordance with the mask pattern or design requirements in the semiconductor process
You could connect to it with any microcontroller over SPI and read out the resistance ratio from the internal ADC
SSR-40DA Solid State Relay 40A (4-32 VDC Input) 2200 uf Features :Circuit Rating: 35V (DC)Introduction : This SSR (Solid State Relay) can switch current loads of up to 40A with a 4 32V DC input and a zero cross trigger control method. Each one of these relays is equipped with four screw terminals (for use with ring or fork connectors) and a plastic cover that slides over the top of the relay to protect the terminals. Input Voltage: 4 32 VDC Output Voltage: 24 380 VDC Turn off Voltage: < 3. 5 VDC Triger Current: 12 Ma max Leakage Current: 5
