Features:

1. The module integrates high-quality Si7021 temperature and humidity sensor from Silicon Lab. It uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure high reliability and long-term stability.

2. Built-in humidity (humidity sensitive) and temperature (thermistor) sensor components, analog to digital converter, signal processing, calibration data and I2C host interface.

3. Factory calibration data is stored in on-chip non-volatile memory, which ensures that the sensors are fully interchangeable and do not require recalibration or software changes.

4. Patented technology for humidity sensing using industry standard, low dielectric constant polymer dielectrics creates low power, monolithic CMOS sensor modules with low skew and hysteresis and excellent long-term stability.

5. Suitable for measuring humidity, dew point and temperature, the module is small in size and accurate to ±0.4 °C, users can embed it in many highly integrated environments. With millisecond measurement conversion time, no need to wait between starting measurement and reading data, 2.54mm pitch interface, convenient for integration testing.

6. The Si7021 sensor chip is connected to an 8-bit single-chip STM8S through the IIC interface. The STM8S leads to the UART interface and the external serial port device for data exchange. The MCU has downloaded the temperature and humidity measurement program, and directly connects the USB to TTL serial board to open the serial port assistant. Or the configuration software in the data can display the current temperature and humidity value in real time, the use is simple and convenient, the module address and output time can be set, which is convenient for multi-point acquisition.

Specification:

·Working voltage: 3.3V

· Temperature range: -40 - 85 ° C (recommended -10 - 60 ° C)

·Temperature accuracy: ±0.4°C (-10 - 85°C)

· Humidity range: 0-100% RH (20% - 80% RH recommended)

· Humidity accuracy: ±3% RH (0-80% RH)

Application range:

Automotive climate control and defogging, baby monitors, continuous positive airway pressure (CPAP) machines, flood and water detectors, gas, fire and smoke detectors, cell phones/smart phones, industrial HVAC/R, notebooks/tablets , laser printers, micro-environment/data centers, PLC and IO modules, remote telemetry devices, thermostats/hygrostats, ventilation and air conditioning systems, weather stations, wind power inverters, windshields and rearview mirror systems, Wireless base station, wireless sensor network

Instructions for use:

1. NRST, GND, SWIM, VCC are STM8S program download debugging interface can be connected

2. RXD, TXD, GND, VCC module UART interface is connected to external serial device

3. Module address range -0-255 configurable; output time interval can be configured with serial port rate

4. Wire properly! Never reverse the positive and negative, causing the board electronics to burn out.
