The invention discloses an environment-friendly type vacuum pump controller belonging to the technical field of electric automobile brake boosting. The controller comprises a housing and a circuit board. A pressure joint used for being butt jointed with a buffer tank is mounted on the housing. An MCU module, an output driving circuit, a voltage detecting circuit and a voltage stabilizing circuit are arranged on the circuit board. A silicon piezoresistive pressure sensor, a temperature sensor used for detecting the operating temperature of the silicon piezoresistive pressure sensor, a first signal amplification circuit used for amplifying signals of the silicon piezoresistive pressure sensor, and a second signal amplification circuit used for amplifying signals of the temperature sensor are also arranged on the circuit board. The induction end of the silicon piezoresistive pressure sensor directly faces a channel and is attached to the entrance of the channel. When the controller works, the MCU module can modify pressure signals according to temperature signals generated by the temperature sensor. The controller can quite accurately detect the pressure in the buffer tank, and a vacuum pump motor can be automatically triggered when the pressure in the buffer tank is higher than the set pressure.
