DS18B20 Submersible Probe Sensor Temperature

The module is based on a touch sensitive IC capacitive touch switch module (TTP223B).
In the normal state, the module produces Low power consumption. When a finger touches the corresponding position, the module output is high, if not touched for 12 seconds, it switches to low power mode. Digital Touch Sensor B21 features:
- Low power consumption
- Input voltage: 2 - 5.5VDC
- Can replace the traditional touch of a button - Four M2 screws diameter 2.2 mm that position the holes for easy installation
- 3-pin control interface:
1- GND
2- VCC
3- Control signal (output pin)
- Power indicators: Bright green LED when the sensor is on

12 Bars of 7mm Hot Silicone Glue Gun features:
- Hot melt adhesive
- Blister packaging
- Includes 12 silicone bars 7.2mm x 100mm
