Selection
Start with voltage, load, and mounting.
Record the controlled load, input range, installation space, sensor direction, and target response.
Technical resources
Use application and wiring inputs to narrow the sensor format before requesting a sample.
Installation
Protect the detection path.
Heat sources, strong airflow, direct sun, vibration, and obstructions can change PIR sensing performance.
Approval
Freeze the sampled configuration.
Match the approved sample to wiring, delay, range, connector, labeling, packaging, and the published record.
