Description

HY-42Q101 Bluetooth low energy single mode module is for AEC-Q100 Qualified Automotive 

Applications , Automotive Device Specification Temperature Grade 2: ( –40°C to +105°C), 

HY-42Q101 is a single mode device, targeted for low power energy sensors and accessories. 

HY-42Q101 offers all Bluetooth low energy features: radio, stack, profiles and application space for automotive applications. The module also provides flexible hardware interfaces to connect sensors. 

HY-42Q101 can be powered directly with a standard 3V coin cell batteries or pair of AAA batteries. 

in lowest power shutdown mode it consumes only 0.15uA and will wake up in few microseconds. 

HY-42Q101 transmission distance of 80 meter or more. (At face to face, free space, 1.2 Meter high from Ground for testing, depend on Antenna gain & Antenna efficiency ).
