Digital barometric sensor delivers fast, accurate pressure readings
A low power draw of 0.6 µA combined with a compact footprint of 3 mm x 3 mm x 0.9 mm makes this high-resolution module ideal for a wide number of handheld, mobile devices including smartphones, tablet PCs and global position equipment as well as fitness equipment and consumer toys. The MS5637’s high resolution temperature output enables operation as an altimeter or thermometer as well.
The MEMS-based MS5637 uses a high-linearity pressure sensor to provide an altitude resolution of 13 cm at sea level for highly accurate measurements. The ADC, with internal factory-calibrated coefficients that do not require additional programming, easily interfaces with any microcontroller via an I2C interface.
Standby power of the MS5637 is less than 0.15 µA at 25°C and supply voltage ranges from 1.5 V to 3.6 V. The sensor operates from 300 mbar to 1,200 mbar over an extended temperature range of -40°C to +85°C, with a long term stability of ±1 mbar per year.
Pricing
Pricing for a MS5637 is less than $1.00 for quantities of 1 million. Delivery time is dependent upon quantity ordered.
