HTU21D+BMP180+BH1750FVI Temperature Humidity Pressure Light sensor

HTU21D + BMP180 + BH1750FVI temperature and humidity barometric pressure sensor lighting triple HTU21D based humidity sensor element is made of a high-performance, next-generation HTU21D temperature and humidity sensors established in size and intelligence of the new standards: it is embedded in a reflow solderable Dual Flat No leads (DFN) package, the bottom surface of 3x3mm, height 1.1mm. After calibration of the sensor output a digital signal, the standard I2C format. Diversification of output, wide operating voltage range, and has a high precision temperature and humidity accuracy. HTU21 series modules are designed for low-power small size application design, with good quality, fast response, anti-interference ability and cost advantages, small size (3x3mm), very low power consumption Sensor Important parameters: Supply voltage: 1.5V-3.6 Humidity measuring range: 0-100% RH Temperature measurement range: -40 ℃ -105 ℃ Maximum power consumption: 2.7uW Of communication: I2C Humidity accuracy range (10% RH to 95% RH): HTU21D ± 2% RH Humidity Hysteresis: ± 1% RH Measuring time: 50ms Annual shift: -0.5% RH / year Response time: 5 s SHT21 SHT20 SHT11 SHT10 have a relatively smaller volume. Meanwhile HTU21D can SHT20 Switzerland, SHT21 full compatibility can be achieved Pin to Pin Pin on hardware, without modifying the circuit board. Software programs and also Switzerland SHT20, SHT21 same can be achieved compatible replacement, without making any changes. Meanwhile HTU21D than Switzerland SHT20, SHT21 has a good price advantage, very cost-effective. BMP180 is a high precision, small size, ultra-low power consumption pressure sensors can be used in mobile devices of its outstanding performance, the lowest absolute accuracy can be achieved 0.03hPa, and low power consumption, only 3μABMP180 uses a powerful 8-pin ceramic leadless chip carrier (LCC) ultra-thin package, can be directly connected with a variety of microprocessor via I2C bus ROHM chip using original BH1750FVI Power supply: 3-5v Light range: 0-65535 lx Sensors built 16bitAD converter Direct digital output, omit the complex calculations omit the calibration Does not distinguish between ambient light Spectral characteristics close to visual sensitivity Available on a wide range of high-precision measurement brightness 1 lux Standard IIC communication protocol Internal communication module includes level conversion, and directly connected to 5v microcontroller io.
