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.\u003c\/p\u003e\n\u003cp\u003eCompact 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.\u003c\/p\u003e\n\u003cp\u003ePower 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.\u003c\/p\u003e\n\u003ch4\u003eFeatures:\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eHigh accuracy in temperature and humidity measurements\u003c\/li\u003e\n\u003cli\u003eDigital output for easy interfacing\u003c\/li\u003e\n\u003cli\u003eLow power consumption\u003c\/li\u003e\n\u003cli\u003eI2C or SPI communication interface\u003c\/li\u003e\n\u003cli\u003eOn-chip calibration data\u003c\/li\u003e\n\u003cli\u003eSmall form factor for easy integration\u003c\/li\u003e\n\u003cli\u003eWide operating voltage range\u003c\/li\u003e\n\u003cli\u003eOften used in various applications including weather stations, environmental monitoring, and industrial automation\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch4\u003ePackage Includes:\u003c\/h4\u003e\n\u003cp\u003e1 x Unwelded GY-SHT45 Digital Temperature and Humidity Sensor\u003c\/p\u003e","brand":"Indian Hobby Center","offers":[{"title":"Default Title","offer_id":43926151659563,"sku":"2394","price":799.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/6796\/1387\/files\/unwelded-gy-sht45-digital-temperature-and-humidity-sensor-400x400.jpg?v=1776170312","url":"https:\/\/www.indianhobbycenter.com\/products\/unwelded-gy-sht45-digital-temperature-and-humidity-sensor","provider":"Indian Hobby Center","version":"1.0","type":"link"}
