The invention discloses a temperature and humidity sensor system based on BLE (Bluetooth Low Energy), which comprises a management module and at least one node module, wherein the management module comprises a management bluetooth unit and a display unit; the display unit is used for displaying received temperature and humidity information; the node module comprises a housing, a power supply unit, a temperature and humidity sensor, a control unit and a node bluetooth unit; the control unit is electrically connected with the power supply unit, the temperature and humidity sensor and the node bluetooth unit respectively; the temperature and humidity sensor is used for sensing temperature and humidity outside the housing and transferring the temperature and the humidity to the control unit; the control unit is used for transferring the received temperature and humidity information to the management module; and the management bluetooth unit is communicated with the node bluetooth unit based on a BLE protocol. The system is simple in structure, convenient to use and very low in power consumption, and requires no wired power supply; a button battery can be used for more than one year; and in addition, nodes independently operate, so that layout, maintenance and adjustment are very convenient.
Description
technical field [0001] The invention relates to the field of electronic measurement, in particular to a temperature and humidity sensor system based on Bluetooth BLE. Background technique [0002] BLE (Bluetooth Low Energy, Bluetooth low energy technology) is a supplement to the traditional Bluetooth BR / EDR technology. Although both BLE and traditional Bluetooth are called Bluetooth standards and share radio frequencies, BLE is a completely different technology. BLE does not have compatibility with traditional Bluetooth BR / EDR. It is designed for small data rate, discrete transmission applications. The communication distance has also changed. The transmission distance of traditional Bluetooth ranges from tens of meters to hundreds of meters, while BLE is stipulated as 100 meters. [0003] ULP performance is made possible by three features of Bluetooth low energy technology: maximized standby time, fast connection, and low peak transmit / receive power consumption. [0004]...
