Abstract: Many factors influence the data acquisition of groundwater, ordinary pressure transmitter can not meet the demands of data collection, this research designs the ultra - low power consumption transmitter for special requirements. Data acquisition was done automatically in the field without the normal power supply. In the design, reducing power consumption to a minimum, saving power maximumly, in order to reduce the number of artificial operation and the minimum working time of the used lithium battery is not less than 6 months. The involved and development intelligent integrated water level (pressure), temperature sensor will install pressure sensor, temperature sensor, automatic zeroing amplifier and low voltage, super low power data acquisition SCM in stainless steel casing of diameter 28 mm and completely put into the water, the distance of data transmission is greater than 500 meters.
