The Sensor-Circuit Design of Bunch and Water Facilities' Monitoring System
Juan Ping Wang · Applied Mechanics and Materials · 2012
Monitoring signal of bunch and water facilities’monitoring system was from photoelectric sensors and pressure sensors, distribution and installation of photoelectric sensors into the seed tubes were analyzed after Choosing the photoelectric sensors, circuit were designed to amplify the output signals which were sended to the 8031 for processing, the sowing monitoring were realized. Circuit were designed after Choosing the pressure sensors to converse the signals A/D by the ADC0809 and send it to the 8031 for processing, water and fertilizer were monitored real-time, so the signals of the whole system were input.
