This is a TTGO T-Higrow ESP32 Wifi Bluetooth Humidity Photometric Electrolyte Sensor Unsoldered. 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.S18B20 waterproof temperature sensor is used for t-higrow and t-watch with the t-grove interface. For example, 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.

Features:

1. It is easy to carry anywhere.
2. the temperature sensor makes it unique because of the sensors’ waterproof property.

Package Includes:

1 x Unsoldered TTGO T-Higrow ESP32 Wifi Bluetooth Humidity Photometric Electrolyte Sensor

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, and transmitters. A humidity Sensor is an instrument used for measuring the moisture content in the environmental air or powders. 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.

Features:

1. Higher accuracy
