KOHLER053 Microwave Sensor User Manual

User Manual

Brief introduction

The microwave sensor is used as human body detector for automatic control.
The sensor adopts frequency modulated continuous wave (FMCW) technique, so has higher ranging accuracy and stronger adaptability compared with doppler sensor.
The sensor can detect distance and motion state of ambient human body in real time, and send corresponding signal to master controller to control automatic opening/closing of cover & seat and auto-flushing.

Notice：

Warning : changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

This Module complies with FCC&ISED radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 1.02cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Please notice that if the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. For FCC, this exterior  abel should follow “Contains FCC ID: N82-KOHLER053”. In accordance with FCC KDB guidance 784748 Labeling Guidelines.
The OEM integrator is responsible for ensuring that the end-user has no manual instruction to remove or install module.
The module is limited to installation in mobile application, a separate approval is required for all other operating configurations, including portable configurations with respect to §2.1091 and difference antenna configurations.
If you desire to increase antenna gain and either change antenna type or use same antenna type certified, a Class II permissive change application is required to be filed by us, or you (host manufacturer) can take responsibility through the change in FCC ID (new application) procedure followed by a Class II permissive change application.
This modular transmitter is only FCC authorized for the specific rule parts listed on our grant, host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification.

Host manufacturer in any case shall ensure host product which is installed and operating with the module is in compliant with Part 15B requirements.
Please note that For a Class B or Class A digital device or peripheral, the instructions furnished the user manual of the end-user product shall include statement set out in §15.105 Information to the user or such similar statement and place it in a prominent location in the text of host product manual. Original texts as following: For Class B

Note : This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

•  Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

For Class A
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

Signal definition of digital output pin

Digital output pin remains low electric level. Once target object moves in the distance of the preset gear, the sensor output pulse signal with special frequency, which would keep till the object moves out of the distance range. The period of the pulse signal is 50 ± 1ms, and the duty ratio of high/low electric level is 50% with high electric level of 5V.

 Certification information
