Beschreibung
Zusammenfassung:	The invention discloses a wireless acquisition node and method based on water environment monitoring. The node comprises micro-sensing units, a signal conditioning and weak signal detection circuit, awireless transmission module and a thermoelectric power generation self-powered module. The number of the micro-sensing units is multiple, and the micro-sensing units are arranged in parallel and used for collecting water body ecological information, converting the water body ecological information into electric signals and sending the electric signals to the signal conditioning and weak signal detection circuit. The input end of the signal conditioning weak signal detection circuit is connected with the micro sensing unit, and the output end of the signal conditioning weak signal detection circuit is connected with the wireless transmission module. The thermoelectric power generation self-powered module is connected with the micro-sensing unit, the signal conditioning and weak signal detection circuit and the wi
