Abstract

An air conditioner control system comprises air conditioners configured to condition an environment in a target space, an integrated controller configured to control the air conditioners based on control parameter data, sensor devices configured to measure the temperature of the target space and transmit measurement data, and wireless master devices configured to create control parameter data based on the measurement data. The wireless master devices each determine sleep times so that at least two sensor devices run out of battery charge around the same time according to the remaining charge amount of each of the sensor devices. The sensor devices each will be in the sleep mode in which power consumption is lower than in the normal mode according to the sleep time decided by the wireless master devices.
