1. Sensing distance: about 3-5 meters
2. Using Doppler radar technology, a microwave sensor module that specifically detects object movement
3. The module has the characteristics of high sensitivity, long sensing distance, strong reliability, large sensing angle, wide power supply voltage range, etc.
4. Widely used in various occasions such as human body induction lighting and anti-theft alarm
5. Adopt special signal processing control chip RCWL-9196
6. Wide working voltage range: 4.0~28.0V
7. Compared with traditional infrared induction PIR, it has penetrating detection ability
8. Blocking time, adjustable distance
9. Can output 3. 3V power supply
Pin function description:
1. 3.3V output voltage, drive current 100mA
2. GND module ground
3. OUT controls the signal output. When there is an object moving in the detection area, OUT outputs a high level; C-TM can set the repeated trigger time. If there is a trigger signal (there is an object moving) within the repeated trigger time, it will continue to output a high level. ;If there is no moving object in the detection area, output low level
4. VIN module power input, 4-28V
5. CDS trigger control signal; less than 0.7V, OUT always outputs low level; greater than 0.7V, the detection works normally, the CDS pin is connected with a photoresistor, and the module detection function can be turned off at night
Adjustment Section Instructions:
1. C-TM: Adjust the repeated trigger time, the default trigger time is 2S, increasing the capacitor capacity will increase the repeated trigger time, the actual calculation of the repeated trigger time can be done as follows, put a capacitor on the C-TM, and test the frequency f of pin 3 of 9196 , repeated trigger time T= (1/f) *32768
2. R-GN detection distance adjustment, connected to a resistor, the detection distance becomes smaller, not connected, the detection distance is about 7m, connected to a 1m resistor, the detection distance is about 5m, the customer can adjust according to the actual situation
3. The internal VCC of R-CDS is connected in parallel with the internal 1m resistor to the CDS pin (that is, 9 pin 9196) through the R-CDS. The CDS is connected to the photoresistor, and the module detection function can be turned off at night, and R can be set according to the actual ambient brightness. -CDS value
Attention should be paid to the application design:
1. There must be no metal shielding in front of the sensing surface
2. There should be more than 1CM space reserved at the front and back of the sensing surface
3. The module is as parallel as possible to the plane of the mounting carrier
4. The application is effective in a certain detection area
5. The component side of the module is the positive sensing side, and the reverse side is the negative sensing side, and the negative sensing side has a slightly poorer sensing effect
6. Microwave modules cannot be used on a large scale in the same area, otherwise there will be mutual interference, and the distance between individual bodies is greater than 1M

At PMC TechLife, we are committed to ensuring our customers are satisfied with their purchases. Our return policy is designed to be transparent, fair, and fully compliant with South African consumer protection laws, including the Consumer Protection Act (CPA) and the Electronic Communications and Transactions Act (ECTA).
We offer distinct return processes based on the reason for your return. Please read the following sections carefully to understand your rights and the procedures for returning an item.
1. Your Right to Return Defective or Faulty Goods (6-Month Warranty)
In accordance with the Consumer Protection Act, if any product you receive is defective, faulty, unsafe, or of poor quality, you have 6 months from the date of delivery to return it. In such cases, you are entitled to a full refund, a replacement, or a repair of the item, at your choice. We will cover all costs associated with the return shipping for defective items.
To be eligible for a defective goods return:
- The return must be logged within 6 months of delivery.
- The item should be returned with all parts and original packaging where possible. We understand that discovering a defect may require opening the packaging or breaking a seal; returns for defective items will be accepted even if opened.
- Our inspection must confirm the issue was a manufacturing defect and not caused by customer misuse, improper installation, or normal wear and tear.
2. Your Right to a 'Cooling-Off' Return (Change of Mind)
In line with the Electronic Communications and Transactions Act for online purchases, you have a 7-day 'cooling-off' period. If you change your mind or ordered incorrectly, you have 7 days from the date of delivery to request a return for a refund or exchange.
To be eligible for a 'change of mind' return:
- The item must be in its original, as-new, and resalable condition, unworn and unused.
- The item must be returned in its original packaging, with all original tags and accessories included. You may open the packaging to inspect the item, but it must be returned undamaged.
- The customer is responsible for the cost of return shipping.
- Important: There are no handling or restocking fees for change-of-mind returns. You will be refunded the full purchase price, as the law grants you the right to cancel "without penalty."
3. How to Start a Return
