HTU21D Temperature and Humidity Sensor Module HTU2X
Price in Sri Lanka

The difference between htu20d and htu21d sensor modules is that the humidity measurement accuracy is different, the software and hardware are fully compatible, and the customer can choose by himself

Based on the high-performance humidity sensor, a new generation of htu20 and htu21d temperature and humidity sensors has set a new standard in terms of size and intelligence: it is embedded in a double-row flat lead-free DFN package suitable for reflow soldering with a bottom surface of 3x3mm and a height of 1.1mm. The sensor outputs a calibrated digital signal in standard I2C format. Diversified output mode, wide working voltage range, high temperature accuracy, and humidity accuracy Htu2x series modules are specially designed for low power and small volume applications, with good quality, fast response speed, strong anti-interference ability, high cost performance, small volume (3x3mm), very low power consumption

Features:

• Important parameters of sensor:
• Power supply voltage: 1.5v-3.6
• Humidity measurement range: 0-100% RH
• Temperature measurement range: - 40 ° - 105 °
• Maximum power consumption: 2.7uw
• Communication mode: I2C
• Humidity accuracy range (10% RH to 95% RH): htu20d ± 3% 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, htu20d and htu21d can be fully compatible with sht20 and SHT21 in Switzerland. Pin to pin can be realized on the hardware pin without modifying the circuit board. The software program is the same as sht20 and SHT21 in Switzerland, which can realize compatible replacement without any modification. Has a very good price advantage, very cost-effective
• Htu20d, htu21d ultra small volume temperature and humidity integrated digital output module is a product with excellent performance. Meanwhile, htu20d and htu21d have great advantages in price, performance and power consumption.
