T-230 Wetness Sensor

A. Specifications:

Battery

LR43

Power

consumption

Max 34mA

Stand-by current 1.5uA

Voltage 2.2VDC – 3VDC

Communication

433.92MHz, FSK, 57.6K bit rate

Sensitivity -104dBm

Transmit power <10 dBm

Address length 16 bit

Operating

temperature range

0 – 60 ℃

B. Functions:

- Clip-on notification

- 64 levels of wetness

- Battery low notification

C. Instructions of use:

1. Clipping

After clipped-on, the pins in wetness sensor will be attached on the two parallel

sensing conductive lines. If the contact is good, the sensor will sound a long “beep”. If

the contact is poor, the sensor will sound 3 short “beeps”. When the sensor is detached,

a “beep” will be sounded.

2. Matching

To enter the code-matching mode, place the sensor on

top of R-138a as the figure.

3. Battery low notification

When the voltage falls to 2.2V, the sensor will sound

“beep-beep”, “beep-beep”, “beep-beep” when it is

clipped on. Replace the battery immediately.

The sensor stops working when the voltage falls to

2.2V.

4. Wetness data transmission and update
