This 1CH mini garage door remote control (S1SM-DC12 & C-1) operates in the 315/433MHz frequency. It can be applied to many devices with voltage AC 110~240V or DC 0~28V because of normally open/ closed contact. It works with momentary mode, which means press and hold the remote button, turn on/open the electrical device; release the button, turn off/close the device. Applications include gate remote control, motor remote control, garage door remote control, light remote control, etc. The transmission distance is about 100m in the open field. We suggest that you’d better use this kit to remote control motor off/on.
