Product Description:
YJJ SHT31-DIS-B2.5KS GY-SHT31-D Temperature and Humidity Sensor
Probe Module Module for Air I2C IIC Communication
Features:
Main parameters of the SHT31 humidity and temperature sensor are as
follows:
Core parameters
Humidity measurement range: 0%-100% RH
Temperature measurement range: -40℃ - 125℃
Humidity measurement accuracy: ±2% RH
Temperature measurement accuracy: ±0.2℃
Operating voltage: 2.15V - 5.5V
Operating current: < 1.5mA
Communication interface: I2C
Package size: DFN8_2.5X2.5MM_EP (2.5×2.5×0.9mm)
Expansion Function
Alarm Mode: Supports extreme temperature and humidity alarms. These
alarms can be reset through software or hardware reset functions.
Anti-interference capability: The PE material casing. It is
recommended to avoid high-temperature environments (> 80℃).
Response time: Humidity measurement takes approximately 8 seconds.
Notes for Attention
When in actual use, it is necessary to pay attention to the working
temperature range of the sensor and avoid exceeding the recommended
limit.
During connection, it is necessary to match the I2C address and the
configuration of the clock line/data line.
SHT31 chip has eight pins:
The Pin Name Comments
1 SDA data pin, input/output
2 ADDR address pin, enter
3 ALENT alarm pin, output;Suspended when not in use
SCL clock pin, input/output
5 VDD power pin, input
6 nRESET reset pin, low level valid, input
7 R useless pin, ground
8 VSS ground pin
Repeatability affects the measurement time of SHT30 and therefore
the energy consumption of the sensor.
The address of the sensor is changed by changing the voltage of
ADDR pin.The default address is when ADDR connects to VSS (0X44),
which can be changed to 0X45.For details on pins, please refer to
the data manual.
