The cat fountain was made from the most common micropump on aliexpress. In a simple version, the pump can be connected directly to a power source for constant water circulation. For autonomous operation of the device, I used parts from a street lamp with a motion sensor on a 18650 lithium-ion battery. Added charging and battery protection on the tp4056 module and an LC filter for the pump. Autonomy without recharging - several days depending on the installation area. Sensor sensitivity 3-5 meters, minimum response time 20 seconds. Since the motor is non-separable, and the cat is fluffy, I added a filter from an ordinary cotton pad. All details were printed from petg.
