STMicroelectronics’, LPS22HH MEMS piezoelectric absolute pressure sensor is said to be so accurate and stable that manufacturers can eliminate one-point calibration (OPC) after soldering to increase throughput and efficiency. With a pressure noise equivalent to 5 cm, the LPS22HH enhances controls such as collision avoidance for drones or other unmanned vehicles.
In addition, temperature compensation is built in, relieving the load on the host microcontroller or application processor. High stability over wide-ranging operating conditions also boosts the performance of devices such as gas meters, weather-station equipment and wearables.
Other features include a 0.9 µA power-down mode, an active power mode drawing just 4 µA at 1 Hz, support for I2C, SPI, and a MIPI I3CSM two-wire sensor-bus interface. The LPS22HH is in production now, packaged as a 2 mm x 2 mm x 0.3 mm 10-lead HLGA, priced from $1.55 each/1,000. For deeper insights, peruse the LPS22HH datasheet.
