The sensors and components in these often battery-powered devices have a high energy requirement which necessitates frequent battery recharging. One bright spot in this field is the new next-generation AMS 5935 low-power pressure sensor which can accurately measure even extremely low pressures in the +/-125 pascal range.
AMSYS has now introduced sustainable sensors to its portfolio with the AMS 5935. The sensors are manufactured in Germany and feature an integrated I2C/SPI interface that outputs calibrated pressure and temperature readings at a very low current consumption (250nA in sleep mode and 2mA during measurements) and a supply voltage in the range of 1.7V to 3.6V.
Based on a piezoresistive pressure sensing element with a state-of-the-art signal processing ASIC in a ceramic DIL package, this board-mount sensor is suitable for PCB mounting. The AMS 5935 has a low total error over a temperature range of –25 to 85°C and an even smaller error at room temperature, making it a highly accurate, low-power pressure sensor.
The AMS 5935 pressure sensor is proving to be a sustainable component in mobile breathing aids and innovative devices whose runtime is to be increased using this intelligent, digital 18-bit pressure sensor.
