TP-206W
Notice:
- Powered by 1 unit 9V battery, there have “+” “-” marked in the sensor case
(battery not include, sometime battery delivery with problems), suggest to use brand "Alkaline" battery, it is longer life
- The 2 battery contacts both inside of the sensor, so the battery cover not with contacts
- If put the detect board on metal, please use a dry paper between detect board and metal
- Upgrade to our double-sided paster / sticker for easy installation anywhere. One part is for the host and the other part is for the water detection board. There are two fixing styles optional for the detect board, as shown in below photo. Choose between two fixing styles based on your needs
Important: Before stick the host and water sensor detection board, ensure that the area where they will be placed is thoroughly cleaned and dried. Make sure that the sticker is securely fixed in place.
Q: False alarm when there are no water leak?
A: The detection board with high sensitivity may experience false alarms in high humidity conditions, you can use a tissue underneath the detect board to prevent direct contact with the detection area, or you can paste the included double side sticker under detect board as below photo.

Thank you for purchasing our alarm system. This product requires a 9V battery, which is not included. We do not manufacture batteries, and including them would increase the product cost and shipping risks.
9V Battery Comparison
To ensure optimal performance, we recommend using a high-quality 9V battery. Below is a comparison of common 9V battery types, including their self-discharge rates, typical lifespans, and estimated runtime under a 150mA load.
| Battery Type | Lifespan (General Use) | Self-Discharge Rate (Per Year) | Estimated Runtime at 150mA Load |
|---|---|---|---|
| Carbon Zinc | 3–6 months | 15–20% | 5–15 minutes |
| Alkaline (Recommended) | 12–24 months | 2–3% | 30–60 minutes |
| Lithium (Highly Recommended) | 3–5 years | <1% | 2–5 hours |
Battery Performance at 150mA Load
-
Carbon Zinc Battery
- Low capacity (~200–400mAh), drains very quickly at 150mA, lasting only 5–15 minutes.
- Not recommened, loses power quickly, even when not in use.
-
Alkaline Battery (Recommended)
- Moderate capacity (~500–800mAh), providing 30–60 minutes of continuous operation.
- Best for general use and offers a balance between cost and performance.
-
Lithium Battery (Highly Recommended)
- High capacity (~1200–1500mAh), lasting 2–5 hours under a 150mA load.
- Best choice for long-term and high-power applications.
Our Recommendation
For the best results, we recommend using brand-name alkaline or lithium batteries from reputable manufacturers such as Energizer, Duracell, or Panasonic.
- For occasional use: Alkaline batteries provide a good balance between cost and performance.
- For long-term reliability and extended operation: Lithium batteries offer significantly longer runtime, lower self-discharge, and better performance in extreme conditions.
