The monitoring of everyday wearables, sports and mobile medical equipment is becoming increasingly widespread. 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 (250 nA in sleep mode and 2 mA during measurements) and a supply voltage in the range of 1.7 V to 3.6 V.

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.

You can find more information about the AMS 5935 on our homepage or visit us at the compamed trade fair in Düsseldorf from November 13 to 16 in hall 8a booth M04.

AMSYS supplies this sensor for pressure ranges of +/- 1.25 mbar and for various differential, relative, bidirectional and absolute pressures from 0 to 2,000 mbar. The DIL version provides vertical pressure ports for tube connections. Alternatively, a space-saving manifold variant for mounting directly to a valve block using O-rings is available. Customer-specific adaptations are also possible. 3D data and a USB starter kit for quick results are available for prototype engineering. Furthermore, AMSYS’ team of consultants is always on hand to provide support where necessary.
