This is a TTGO T-Higrow BME280 Wifi Bluetooth-Unsoldered (Without Humidity Photometric Electrolyte Sensor). The capacitive soil moisture sensor differs from most of the resistive sensors on the market, using the capacitive sensing principle to detect soil moisture. It avoids the problem that the resistance sensor is easy to corrode and greatly prolongs its working life. It can be used with t-higrow to test the temperature and humidity of flowerpot soil and environment, as well as the water temperature of fish tanks when raising fish. Of course, it can also test other temperatures as long as you want.

B3950 10K NTC waterproof High precision thermistor temperature Sensor 5 x 25mm with XH2.54 Connector can be used to measure temperature in a variety of applications.

The sensor has stainless steel 5 x 25mm tip with an XH2.54 connector with a 4-meter cable. It is Negative thermal coefficient (NTC) will decrease. But the formula in practice is not linear,  so sometimes an accurate table of measurements is better than the linear formula. These measurements can usually be found in the datasheet that accompanies the thermistor.

Specifications and Features:

1. Probe sheath material: Stainless Steel
2. Style: B3950 10K
3. Resistance value: 10K ± 1%
4. Measurement range: -20 to 105 °C
5. Cable Length: 4-meter
6. Size of probe: 5 x 25 mm
7. Output wires: 2
8. Typical Dissipation Constant: 5mW/ °C
9. Probe insulation: >100MOhm

Package Includes:

1 x B3950 10K NTC Thermistor Temperature Sensor 5*25mm with XH2.54 Connector with 4-meter Cable

These Humidity Sensors can be used to detect the environmental relative humidity. Used in many end products such as air conditioners, humidifiers, dehumidifiers, hygrometers, recorders, transmitters.

Most measurement devices usually rely on measurements of some other quantity such as temperature, pressure, mass or a mechanical or electrical change in a substance as moisture is absorbed. From calculations based on physical principles, or especially by calibration with a reference standard, these measured quantities can lead to a measurement of humidity. Modern electronic devices use temperature of condensation, or changes in electrical capacitance or resistance to measure humidity changes.
