This guide serves as a functional datasheet and technical overview to help you integrate the HW-416-B into your next project. 1. Technical Specifications
Leo stepped back. He waited sixty seconds for the sensor to calibrate—a "warm-up" period mentioned in the specs. He stood perfectly still. The LED on his board remained dark. Then, he slowly reached for a chocolate bar.
