1. DC operating voltage must meet the value is too high and too low will affect the performance of our module requirements, and requires a well-regulated power supply must be filtered. Customers are advised to use the power transformer, and after a three-terminal regulator chip voltage regulator, and through the 220UF and 0.1UF capacitor filter supply. 
 
2. as far away from the body when debugging sensing area, although sometimes the body is not in front of the module, but the body is too close from the module, the module can also be induced, resulting been output. Do not touch the body when debugging circuit, it will affect the module. More scientific approach is the output of an LED or a multimeter terminated, the module is covered with a newspaper. And so two minutes later to see whether the module has been output.
 
3.When the module is not connected to the load can work, connected to the load of work disorder.
Solution is as follows: A, power section plus inductor filter. B, using load and module voltages using different methods, such as: load using 24V operating voltage, the module uses 12V operating voltage, during a three-terminal regulator isolation. C: using a higher capacity power supply.
 
4. Human body sensing module can only work indoors and work environment should avoid sunlight, direct exposure to intense light, if the work environment has a strong RF interference, shielding measures can be adopted. In case there is a strong air flow interference, close windows and doors or prevent convection. Sensing area to avoid facing the fever appliances and objects
