I am searching for a motion detector controls a solenoid valve which works in a tank for hand-washing. Answer from supplier: We recommend this Infrared PIR Motion Sensor Model of 0040101. The module can accurately detect any moving objects within the detective range and commonly be used to detect human body movement. It has higher sensitivity and broader detective range than others. The motion sensor detector will work with the solenoid valve. Wire the solenoid valve to the detector according to the wiring diagram. When someone puts his hands under the tap, the PIR motion sensor detector will detect and indicate the solenoid valve installed on the tap to open. The water will trickle out from tap for hand washing. It lasts about 20 seconds. The water will stop trickling out after 20 seconds. Online shop:  http://www.carymart.com/

Bird damage to the crops is a serious problem for many farmers. LP gas bird scarer is commonly employed by arable farmers to scare birds such as pigeons and crows and prevent them from eating crops. One customer bought a LP gas bird scaring device and he was planing to use rf remote control to operate the solenoid valve of the device. The nominal voltage is 12vdc. Transmitting range is supposed to be about 1000m. We suggest him to choose rf remote control system with magnetic mount antenna model of 0020250 (S1U-DC12-ANT2 & CB-1). Its theoretical remote distance is up to 2000m. Three working modes Toggle, Momentary and Latching are to select from. Wire the solenoid valve to the receiver according to the wiring diagram, he can control the LP gas bird scarer far away by the remote transmitter.
