bitsensing In-cabin Board

bitsensing MOD620

bitsensing MOD620 reliably detects in-car passenger presence and location. It can also detect in real-time the presence of a child left in a car, even when the car is shut down and locked as well as monitor the vital signs of occupants and send an alert if there are any abnormalities.

 The 120-degree field of view combined with the customizable detection range up to 2.5m provides an increased level of performance. Privacy concerns are also eliminated with the MOD620 as it does not rely on cameras for presence detection. 

 The rearrangeable antenna in the MOD620 allows for customization in channel length compensation, Field of View, and matching circuits for transmitters and receivers. Bitsensing’s unique expertise in customizable antenna design allows for a quick and efficient process in matching specific in-cabin requirements for any vehicle.

The MOD620 is a customizable cost-efficient radar that works in high-speed cars, day or night, with no interference to seatbelts
