This is HR-MaxTemp -Temperature Compensation Sensor. The HR-MaxTemp sensor, when connected to the HR-MaxSonar line of sensors, allows for automatic temperature compensation of speed of sound changes over temperature.
The HR-MaxTemp is designed to be used alongside the HR-MaxSonar sensors. The HR-MaxSonar sensor upon power-up will automatically detect an attached temperature sensor and begin to apply temperature compensation for the speed of sound changes to all range outputs.
Also, Do NOT forget to check our ultrasonic sensors category which includes the range of sensors from brand Maxbotix,
The HR‑MaxTemp is compatible with the following sensor lines:
1 x HR-MaxTemp PCB
1 x 3 feet of cable
A heat Shrink
