Result description
One of the significant challenges for any autonomous application is to keep the standby power low enough for the battery to last when power is not generated. The MS1089 temperature sensor uses no active current between measurements, which means that only standby current flows. The standby current for the MS1089 is less than 5nA, making it ideal for autonomous applications.
The AMANDA Consortium is introducing, designing, and developing a maintenance-free, miniaturised and easily deployable Autonomous Smart Sensing Card – ASSC for environmental sensing and for asset and people tracking/monitoring in smart living and working environments. Although the market today offers a wide range of autonomous devices, devices are rarely autonomous and multisensory. The ASSC’s advantage over existing products on the market is its autonomy of 10 years of operation. Furthermore, a significant advantage of a multi-sensor card is the ability to measure multiple sensors simultaneously.
One of the major challenges for any autonomous application is to keep the standby power low enough for the battery to last when power is not generated. The MS1089 temperature sensor uses no active current between measurements, which means that only standby current flows. Typically, the standby current for the MS1089 is less than 5nA making it ideal for autonomous applications. Another challenge is to have a low minimum voltage. The MS1089 is designed with an operating voltage from 1.8V to 3.6V. This range covers the most prevalent supply voltage settings encountered in current battery-powered or autonomous applications. The peak current during temperature measurement is 70µA, which is very suitable for the types of batteries used in autonomous applications. Average current is 28nA with one measurement per minute making the MS1089 “best in class” with respect to current consumption. Typical accuracy is ±0.3°C from 10°C to 50°C, which fits well for environmental monitoring. Measurements can be started and the temperature can be read digitally via the I2C bus. Alternatively, measurement can be started by driving a trigger pin TM low for a short time.
Addressing target audiences and expressing needs
- Business partners – SMEs, Entrepreneurs, Large Corporations
- Expanding to more markets /finding new customers
- Collaboration
The Consortium is looking for SMEs and industries (such as sensor manufacturers, system integrators, original equipment manufacturers and solution providers) interested in the applications of the ASSC and/or adapting the card to specific applications and needs. Moreover, companies, universities and R&D institutes interested in the further development of the ASSC and the individual HW/SW components are sought. Next to that, the individual partners in the Consortium are looking for partners interested in the use or further development of the individual HW/SW components developed for the ASSC.

R&D, Technology and Innovation aspects
The development started in 2019 and the first silicon has been extensively evaluated using prototype packaging. Chip-Scale-Package (CSP) samples (1.22mm x 1.145mm) are being manufactured now and will be available in Q1 2022. This small CSP package can be soldered using a normal reflow process.
