When the SmartRock sensor is installed inside concrete as recommended, it can transmit up to 40 ft (12 m). When the black transmitter is exposed, the range of the wireless signal can be up to 100 ft (30 m).  Longer connection range can be obtained with the SmartRock-Long Range in conjunction with the SmartHub-Long Range with which data can be transmitted for up to (300m) when the body of the sensor is embedded at recommended depth and up to 1000ft (800m)  when the body is placed outside the concrete.
