6.2 Increase sensitivity by parameter adjustment
To increase the sensitivity further, the user must:
1. Find out the noise floor value of the system
2. Set the threshold above the noise floor
To find out the noise floor value, the user must empty the detection area so no one is inside. Put the radar
module into a product casing so it will have a temperature similar to the product environment, as temperature
can affect the noise floor. Record the macro and micro level for a period of time, and take the maximum
reading as macro and micro noise level. The threshold level can then be set to 15 to 20 percent above noise
level.
