Description BEAWER - Boosting Heater Power Controller
Beawer PT1 is prototype for compact device enabling precision testing and operation of MEMS (micro-electro-mechanical system) heater devices. It is designed to deliver up-to 5W into a platinum-based microsystem heater, while obtaining information about heating element resistance by 4-wire sensing interface. Beawer involves double DC-DC conversion circuitry with 3V..6V inputs, which generates constant internal 3.3V and 5V supplies and variable heater voltage up to 25V. Linear heater current controller enables currents up to 1A with minimal power dissipation due to variable supply voltage. The heater resistance is derived differentially by superposing 25Hz AC current variations into the DC value and measuring the corresponding AC part of heater voltage. Analog signal conditioning circuitry involves differential stages for heater current and voltage measurements and subsequent low-pass pre-filtration to 400Hz in 3-pole Butterworth linear filters. After 14-bit ADC conversion, the DC and AC voltage and current values are processed in dsPIC33FJ128GP804 digital signal controller. Digital interface to the Beawer controller includes USB, SPI and RS485 physical layers. The system can be operated and supplied just from PC USB interface, however with lower power output up to 2W.

In framework of WP1 package, LOX Technologies provided an analysis of actual state and specification of physical, electronic and sensing properties of gas sensors, necessary electronic components and systems, as well as communication interfaces. Thermal model of a MOX sensor has been laid out to support design of heater electronic driver circuitry in the first part of the Feasibility Study on Readout Approaches.
Within the WP3 package, our first task was evaluation and selection of architecture, circuitry and components for sensor readout following criteria for optimal relation of properties, costs and system efficiency. Several heater driver and sensing resistance readout circuitries have been laid out and analyzed for precision, parametric sensitivity and range, and a summary with specification of costs, efficiency and design complexity has been given in the second and third part of the Feasibility Study.
The advanced types of readout circuitry we recommended in the Feasibility Study on Readout Approaches have been utilized in our design of precision gas sensor module, which was partially available as prototype in the late of 2014, so we were able to report practical properties of the CC/CV method at second consortium meeting in Cork in November of that year.

Description SENGA - Precision Gas Sensing Module and Docking Station
SENGA is a multi-channel gas sensing system comprising set of independent intelligent modules and a docking station for up-to 16-channel configuration, with its prior mission in precision gas sensor characterization and long-term sensor data acquisition. Intelligent SENGA modules come with state-of-the-art power-efficient boosting circuitry, enabling utilization of a wide range of gas sensors with up-to 25V, 10W power requirements at one side, or novel micro-heating elements with power requirements down to 10mW, on the other. Two independent resistance measurement inputs found at each module, which span more than 6 orders of magnitude, can be utilized for single or differential gas concentration measurements, as well as an independent feedback for heater or ambient temperature data. By default, the module is equipped with on-the-fly temperature measurement in the platinum heater circuitry utilizing DC current-voltage method. SENGA modules are equipped with RS485 industrial serial bus that enables connection of up-to 64 modules with the same host. To provide housing and docking for multiple modules, SENGA docking station in industrial 19'' case, involving 16 module slots, integrated power supply and a USB/RS485 bus converter, is readied.
