Description:
SHT20 Temperature Humidity Sensor
RED—————————3.3V
GREEN—————————SDA
YELLOW—————————SCL
BLUE—————————GND
Feature:
The SHT20 digital temperature and humidity sensor is based on digital sensing technology and offers high reliability and long-term stability. Full-scale calibration, two-wire digital interface, can be directly connected to the microcontroller, greatly reducing development time, simplifying peripheral circuits and reducing costs. In addition, it is small in size, quick in response, low in energy consumption, immersible, strong in anti-interference ability, integrated in temperature and humidity, combined with dew point measurement, and cost-effective, making the product suitable for a variety of applications.
Technical Parameters:
1. Humidity measurement range: 0~100%RH.
2. humidity measurement accuracy: ± 3% RH
3.temperature measurement range: -40 ~ 125 ° C
4. temperature measurement accuracy: ± 0.3 ° C
5. working voltage: 2.1 ~ 3.6VDC (please note: do not use 5V power supply!!!)
6. I2C interface outputPackage Included:
1PC*SHT20 Digital Temperature and Humidity Sensor
SHT2000 Temperature Humidity Sensor
Setting method: Start value <stop value (program automatically determines working mode is heating/humidifying mode)
Setting method: Start value > stop value (the program automatically determines the working mode is cooling/dehumidifying mode)
Heating/cooling mode setting
Setting mode: setting (starting temperature): Press and hold the ▲ button to start the temperature flashing. Use ▲▼ key to set the starting temperature value.
Setting (stop temperature): Press and hold the ▼ button to stop the temperature flashing. Use ▲▼ to set the stop temperature value.
Heating use case: control the water heater, heat to 65 ° C to stop, the temperature drops back to 50 ° C and start heating again
The first step: heating mode, starting temperature <stop temperature
Step 2: Press and hold the ▲ button to start the temperature flashing. Use ▲▼ to set the starting temperature to 50 °C.
Step 3: Press and hold the ▼ button to stop the temperature flashing. Set the stop temperature to 65 °C with ▲▼ keys, and the setting is completed!
Refrigeration use case: use in the farm, the fan is ventilated to 26 ° C to stop, the temperature is raised to 30 ° C and the ventilation is started again.
The first step: cooling mode, starting temperature > stop temperature
Step 2: Press and hold the ▲ button to start the temperature flashing. Use ▲▼ to set the starting temperature to 30 °C.
The third step: long press the ▼ button to stop the temperature flashing, set the stop temperature to 26 °C by ▲▼, the setting is completed!
Humidification/Dehumidification Mode Settings:
Setting (start humidity): Press and hold △ key to start the humidity value flashing. Set the humidity value by △ ▽ key. Set [Stop Humidity]: Press and hold △ key to stop the humidity value flashing, and set the humidity to stop by △ ▽ key value.
Humidification example: fresh supermarket humidification, control humidifier 50% RH began to humidify, humidified to 80% RH to stop humidification. Setup steps:
Step 1: Press and hold the △ button for 3 seconds to start the humidity value flashing, and set the starting humidity value to 50% RH.
Step 2: Press and hold the ▽ button for 3 seconds to stop the humidity value flashing. Set the value to 80% RH. After the setting is completed, the button will be operated for 5 seconds without returning to the normal display state.
Dehumidification example: workshop control exhaust dehumidification system, humidity 70% RH starts dehumidification, humidity 40% RH stops dehumidification
Setup steps:
Step 1: Press and hold the △ button for 3 seconds to start the humidity value flashing, and set the starting humidity value to 40% RH.
Step 2: Press and hold the ▽ button for 3 seconds to stop the humidity value flashing, set the value to 70% RH, the setting is completed, the button does not operate for 5 seconds, and automatically returns to the normal display state.
