GY-SHT45 Digital Temperature and Humidity Sensor

This is Unwelded GY-SHT45 Digital Temperature and Humidity Sensor. The GY-SHT45 is a digital temperature and humidity sensor, a part of the Sensirion SHT4x series. Capable of providing precise measurements of temperature and humidity. Designed to operate efficiently with minimal power requirements, suitable for battery-powered applications. Typically includes on-chip calibration data for accurate readings without requiring external calibration.

Compact design for easy integration into different devices or projects. Can operate within a broad range of supply voltages. Suitable for a range of applications including environmental monitoring, weather stations, HVAC systems, and industrial automation due to its ability to measure both temperature and humidity accurately.

Power Pins: Vin this is the power pin. The chip can use 2.5-5VDC for power. To power the board, give it the same power as the logic level of your microcontroller e.g. for a 5V micro like for Arduino, use 5V. For a 3.3V controller like a Raspbery Pi, connect to 3.3V GND common ground for power and logic I2C Logic pins: SCL I2C clock pin, connect to your microcontrollers I2C clock line. This pin has a 10K pullup resistor to Vin SDA I2C data pin, connect to your microcontrollers I2C data line. This pin has a 10K pullup resistor to Vin Other Pins: ADR This is the I2C address selection pin. This pin has a 10K pull down resistor to make the default I2C address 0x44. You can tie this pin to Vin to make the address 0x45 RST Hardware reset pint. Has a 10K pullup on it to make the chip active by default. Connect to ground to do a hardware reset! ALR Alert/Interrupt output. You can set up the sensor to alert you when an event has occurred.
