Background
The on-line monitoring of the room temperature refers to a temperature measuring mode which utilizes a digital display type thermometer arranged in the indoor space of the building to continuously and automatically measure the room temperature, and remotely transmits the measured room temperature data to a management system of an upper computer through communication equipment for displaying for monitoring by managers.
For the room temperature online monitoring equipment, such as switch type room temperature online monitoring equipment, the intelligent temperature monitoring equipment is advanced Internet of things sensing equipment integrating a flashlight switch and a digital display type temperature meter.
