CDM324 Traffic Control Sensor Module

the cdm324 motion sensor module is equipped with a microwave sensor along with a driver board. the driver board includes radar sensor amplifier circuits, a power block, and an output block. the power block features a switching regulator with an input range of 8 to 25 volts. the output block consists of a 3 amp relay, and the range and timing of its operation can be specified using potentiometers. microwave radar sensors can detect the distance to a target by transmitting and receiving radio waves. compared to other distance detection sensors, radar sensors are smaller, lighter, and have a wider detection range. radar sensors operate in harsh conditions and are capable of penetrating non-metallic objects, dust, smoke, and fog. additionally, these sensors can detect multiple targets simultaneously. the cdm324 sensor is a motion sensor that uses the doppler effect to detect movement. this sensor can identify any type of movement within a specified distance and convert it into an electrical voltage. the frequency of this electrical voltage has a direct relationship with the speed of the object passing in front of the sensor. the cdm324 sensor module has many applications for access control and traffic management.
