                Abstract: Aiming at the current seepage measurement field, there is a problem that the measurement accuracy of seepage velocity is not high and it can not be measured for a long time, a new seepage measurement method is proposed. This method is to directly heat the seepage flowing through the small pipe diameter, and use the Pt100 temperature measuring resistor to measure the temperature change before and after heating, so as to calculate the seepage flow rate. On the basis of this method, an underground thermal seepage measurement sensor was designed and manufactured. The sensor uses the Lora module to complete the remote wireless transmission of data, realizes real-time online monitoring, uses a solar power system to achieve a good energy supply, and maintains the long-term stable operation of the sensor. Through the seepage velocity measurement experiment on the designed seepage sensor in sand, it is proved that the sensor can effectively measure the seepage velocity, the measurement range is 0.000 1-0.001 3 m/s, and the maximum measurement error is about 6.72%.
