At present, most car trunks on the market require a key or manual button to open. When the owner is holding a large item, they must place it on the ground before manually opening the trunk, which can be inconvenient. This product addresses this issue by providing a hands-free solution. It is installed inside the rear of the car and emits microwaves downward for detection. If the sensor detects a valid kick within the sensing area, it outputs a corresponding signal based on signal strength to control the opening of the tailgate. Normal operation: Approach the bumper sensing area with your foot and then leave the area. Once this motion is completed, a trigger signal is generated. The system is designed to avoid false triggers from common environmental factors such as stairs, stones, branches, rough roads, plastic bottles, or car wash conditions. Compatible with most vehicles. Installation instructions: 1. Locate the proper position on the rear bumper of the vehicle. 2. Clean the sensor installation area. 3. Remove the backing from the double-sided tape on the sensor (the side with the tape should face the ground). 4. Securely attach the sensor to the rear bumper panel (inside the bumper). Ensure the sensor area is not obstructed by metal objects such as iron or aluminum. After powering on, wait 20 seconds for the self-test to complete before performing kicking or sweeping motions under the sensor. Note: - The sensor recognizes only one type of motion at a time—either a single kick or a single sweep. - After each motion, wait at least 2 seconds before initiating another action. - The system is designed to function only when the vehicle is in an appropriate operational state. Type: Car kick sensor Color: Black Material: ABS plastic Package Contents: 1 x Kick sensor kit Only the items listed above are included.
