Item type:Publication, Wireless Carbon Monoxide Level Control and Monitoring SystemThis paper proposes an online carbon monoxide control and monitoring system. The proposed system comprises an MQ-7 CO gas sensor module, a DHT11 digital temperature and humidity sensor module, an ESP8266 module, and a Relay Module. The ThingSpeak platform is used to create HMI for online monitoring of CO level, temperature, humidity, and status of the ventilation fan. This proposed system can measure CO and monitor all parameters of measurement data, alert users when CO values exceed the set value. In addition, the measured CO values are used to control the ventilation system operation (ON or OFF) to maintain the CO at a non-harmful level. The experiment testing and results with three conditions show that the proposed system can measure and monitor CO level, temperature, and humidity online with satisfying values. The ventilation fan can operate with function as a design procedure and maintain CO at a non-harmful level. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Resistive-Sensor Interfacing Circuit for Remote Measurement Using CFOA(2024-01-01); ; ; Kaewpoonsuk, AnuchaAn alternative approach to implementing an interfacing circuit for resistive sensor-based remote measurement is presented. The proposed technique uses a Current Feedback Operational Amplifier (CFOA) as an active building block to produce an output voltage linearly related to the resistance of the sensor. Moreover, the accuracy of the output voltage is improved by the enhancement of CFOA. In addition, the proposed circuit provides compensation for the effects of lead-wire resistance. The performance of the proposed technique is discussed in detail and confirmed by PSPICE program simulation and experimental implementation. The resistance decade box is used in the experiment. The maximum error on the output voltage of the experimental results is about 0.4234 %. The experimental results show that the proposed technique provides good performance. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Integration of WirelessHART devices into mitsubishi PLC for plant monitoring(2018-06-08); ; This paper presents a technique to integrate WirelessHART devices into Mitsubishi PLC for plant monitoring. The integration between WirelessHART devices and Mitsubishi PLC is based on OPC technologies. DASMTEthernet OPC and DASMBTCP OPC are used to communicate between WirelessHART devices, Mitsubishi PLC and SCADA software. Commercial WirelessHART devices and Mitsubishi PLC are used in experiment. The experimental testing with Pneumatic object moving plant shown the proposed system can monitor pressure and temperature of air compressor and stop the operation of Pneumatic object moving plant when the pressure and temperature of the air compressor are out of defined range. The experimental results illustrated here are useful people interested in the use of measuring multiple parameters for monitoring conditions of industrial plant controlled by Mitsubishi PLC including commercial PLC. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, A novel resolver-to-DC converter based on OTA-based inverse-sine function circuit(2008-12-01); ; ; A new technique for realizing the resolver-to-DC converter using the OTA-based inverse-sine function circuit is presented. The proposed converter comprises the demodulator, absolute detector, minimum detector, ± unity-gain amplifier, controlled signal logic circuit, and OTA-based inverse-sine function circuit. The output voltage is linearly proportional to the resolver angle with maximum absolute error of about 0.195%, which is less than the error from the conventional resolver-to-DC converter based on the similar OTA-based inverse-sine function circuit. PSPICE simulation and experimental results verifying the performances of the proposed circuit are in close agreement with the expected values. © 2008 SICE. - Some of the metrics are blocked by yourconsent settings
