HTU21D Arduino Temperature and Humidity Sensor Module เซ็นเซอร์ความชื้นและอุณหภูมิแบบ I2C GY-213V-HTU21D
โมดูล HTU21D เซนเซอร์วัดความชื้นและอุณหภูมิ ใช้ไอซีเบอร์ HTU21D ใช้ไฟเลี้ยง 3.3V ต่อสายไฟกับ Arduino เพียง 2 เส้น ติดต่อแบบ I2C วัดค่าอุณหภูมิได้ที่ค่าความผิดพลาดไม่เกิน ±0.3C และวัดค่าความชื้นได้ที่ค่าความผิดพลาดไม่เกิน ±2%
HTU21D Temperature and Humidity Sensor Module
Temperature and Humidity Sensor The HTU21D sensor module replaces the simple SHT15 Arduino
Based on a high performance humidity sensing element, the next generation HTU21D temperature and humidity sensor sets new standards in terms of size and intelligence: it embeds a dual flat, leadless DFN package for reflow, with a 3x3mm bottom surface and a height of 1.1 mm. Sensor output calibrated digital signal, standard I2C format. Diversified output, wide operating voltage range, while high temperature accuracy and humidity accuracy. Designed for low power and small volume applications, the HTU21 Series modules are characterized by good quality, fast response, strong anti-interference ability, and high cost performance. The tiny volume (3x3mm), low power consumption
Sensor important parameters:
Supply voltage: 1.5V-3.6
Humidity measurement range: 0-100% RH
Temperature measurement range: -40 ℃ -105 ℃
Maximum power consumption: 2.7uW
Communication method: I2C
Humidity Accuracy Range (10% RH to 95% RH): HTU21D ± 2% RH
Humidity Hysteresis: ± 1% RH
Measurement time: 50ms
Annual drift: -0.5% RH / year
Response time: 5 s
At the same time, the HTU21D can be fully compatible with the SHT20 and SHT21 in Switzerland, and the Pin to Pin can be implemented on the hardware pins without modifying the circuit board. Software program and the Swiss SHT20 , SHT21 the same, compatible replacement can be achieved without any changes. Has a very good price advantage, very cost-effective. HTU21D ultra-small volume of digital temperature and humidity digital output module is a good performance products. At the same time, HTU21D in the price, performance, power consumption and other aspects have great advantages.
