Overall Installation Instructions:
As far as possible, it should be placed at a higher and more open place. It is recommended to be 1m/3.3ft above the ground; avoid placing metal objects around the sensor to prevent the wireless signal from being weakened by shielding; electronic interference will be caused by the following various objects, so Should be avoided: generators, high-current equipment, high-voltage relays, transformer, etc.; vibration or blow may also become a source of interference, so the equipment should be as static as possible when the equipment is installed.
Do not install the device outside of the sensor's measurement range, as this will prevent the product from working properly and cause permanent damage to the sensor.
Please do not tear up the label on the product case with important information such as the product ID.
Please do not disassemble the product, and the company will not be responsible for any damage caused.
