PROBLEM TO BE SOLVED: To provide a compact and simple communication module, a communication system and a sensor system. SOLUTION: The processing part of a communication module 200 executes address registration command reception processing; address registration processing; post-stage side output control processing and pre-stage side output control processing. In the address registration command reception processing, when a module address is not registered and the pre-stage side input terminal is in a first level, the address registration command transmitted from a main unit 100 is received by a communication function. In the address registration processing, the module address is stored in a memory according to the received address registration command. In the post-stage side output control processing, the post-stage side output terminal is shifted from a second level to the first level after the address registration command reception processing. In the pre-stage side output control processing, the pre-stage side output terminal is shifted from the second level to the first level when the post-stage side input terminal is in the first level after the address registration processing.
