“…Both CuO and CTO layers are printed in six stacked layers on top of the interdigitated Pt-electrodes of the MEMS chip. We determine the resistivity of the layer by means of a time-to-digital conversion method [41]. This approach minimizes the power consumption and the cost as compared to using analog-to-digital converters (ADC).…”

This manuscript describes the design considerations, implementation, and laboratory validation of an odor sensing module whose purpose is to support people that suffer from incontinence. Because of the requirements expressed by the affected end-users the odor sensing unit is realized as a portable accessory that may be connected to any pre-existing smart device. We have opted for a low-cost, low-power consuming metal oxide based gas detection approach to highlight the viability of developing an inexpensive yet helpful odor recognition technology. The system consists of a hotplate employing, inkjet-printed p-type semiconducting layers of copper(II) oxide, and chromium titanium oxide. Both functional layers are characterized with respect to their gas-sensitive behavior towards humidity, ammonia, methylmercaptan, and dimethylsulfide and we demonstrate detection limits in the parts-per-billion range for the two latter gases. Employing a temperature variation scheme that reads out the layer’s resistivity in a steady-state, we use each sensor chip as a virtual array. With this setup, we demonstrate the feasibility of detecting odors associated with incontinence.

“…In order to save energy we employ a wake up approach that relies on this reaction: In the sleep mode, the hotplate is not powered permanently and the system checks the layer's resistivity once a minute using a time-to-digital read-out technique [15]. As soon as an odor event triggers the phase transition and a conductive path of copper sulfide (CuS) appears, the sensor node wakes up and switches into measurement mode.…”

Abstract:The localization of bad odors is a long standing issue with high relevance for affected people because of the health and safety implications. In order to enable the detection and localization of bad odors we propose a wireless, low-power consuming sensor network. The sensor nodes are designed to wake-up upon initial detection of a bad odor to then start to measure the strength of the odor. Taking into account the spatial variation of the bad odor as well as environmental parameters the odor source may be identified. After the odor vanishes the sensor nodes return to sleep mode.

“…In [14], which deals with the sensory network with communication layer using radio signals, the individual sensory nodes (sensing node) are implemented on the microprocessor STM32L1. The problem of the sensor physical connection to the microcontroller is discussed in [15], where Reverter describes the physical effects that can occur during the measurement itself. The author also suggests connections which eliminate undesired transition effects.…”

Sensory networks are part of a solution to monitor the required physical variables in the area of interest. Their type, the used communication protocol, plays an important role in the parameter of their complexity. One of the economical solutions is the usage of a 1-wire communication network that requires only 2 physical wires. The individual sensors or the nodes of the communication network are connected in parallel. The goal was to design and implement a universal low-power 1-wire bus module with a fully implemented 1-wire standard. As a platform for the development of such module, STM32-based microcontroller was chosen. The main advantage of this solution is the ability to utilize a sensor from a large variety of available sensors with a standardized communication interface. Our solution of the universal 1-wire module provides a single interface for sensors with different communication interfaces, while it still communicates with the standard 1-wire bus controller.
