Abstract
A wireless sensor unit installed in the same machine body includes a sensor, an analog/digital signal converter and a wireless signal transceiver; the sensor and the analog/digital signal converter are connected for converting a value detected by the sensor into a digital signal and synchronizing a transceiver at a remote end for repeatedly transmitting the digital signal one way in a predetermined time slot by switching different frequencies. In the meantime, the transceiver at a remote end is used for receiving signals from different wireless sensors in a one-to-multiple manner, and the distribution of the time slots for receiving signals is used for identifying the source of the signals, and then the digital signals are stored, computed, printed and displayed. The wireless sensor unit keeps transmitting the signals one way by different frequencies, so as to constitute a simple and reliable transmission method, which can be applied directly for laboratories, factories, incinerators, weigh stations, hopper/tank scales and any other application by a transceiver at a remote end for collecting readings from different sensors.
