FunctionInfrared detection: 8 channel infrared detector hunting module, with 8 tracking modules infrared detection sensors, simple and easy to useTotal 8 sensors: D1 - d8 mark on the module corresponds to 8 sensors left to right, clearly readableAnalog output: the output mode D1 - d8 is analog, and after electricity is a normal high level, with stable connection performance. 1v voltage value change range: using the sensor obstacle coverage, the voltage value of D1 - D8 will be reduced based on the distance of the obstacle, and the switching range will be within 1v. Excellent PCB: High quality PCB materials with reliability and miniaturization, good maintainability and interchangeability
