Infusion Level Monitor Using Capacitive Touch Sensing

This is an infusion level monitoring solution to detect the remaining amount of liquid using low power consumption and capacitive touch sensors. Users can monitor the remaining liquid amount via Bluetooth^® Low Energy (LE) or Wi-Fi in a remote location (e.g., nurse station). This solution can be applied to not only infusion but also to various applications with liquid tanks.

System Benefits​:

• Capacitive touch sensing and system control are realized using the RX140 32-bit MCU.
• The simple configuration of only the electrodes enables the detection of the remaining amount of liquid, which contributes to a reduction in BOM cost.
• Low power consumption Wi-Fi + Bluetooth LE module and RX140 MCU for long-term operation, ideal for battery-powered applications.
