Validation of EMI
Minda Instrument Ltd
Team Member
ACADEMICPROJECT, GREEN HOUSE MANAGEMENT
- The objective of this project is to design microcontroller-based circuit to monitor & control the values of temperature, humidity, moisture & sunlight of environment that are continuously modified & control to optimize maximum plant growth &yield
- The controller usedAT89C51 IC a 8 bit microcontroller with 4K byte flash memory to communicates with the various sensors in real time &there is a integrated Liquid crystal display (LCD) for real time display of data acquired from various sensors &devices
- The analog parameters measured by sensor are then converted to digital value by ADC 0808 & then processed to microcontroller
- The various sensors used are LM35 temp sensor, LDR for light sensor with LM 358 op-amp with relay driver IC 2803.
