Abstract
Abstract : The research work was undertaken on “Development of Solar Powered Ultrasonic System for Farms.” A Solar powered ultrasonic system was developed consisted of 10 W SPV panel, 12 V; 7 Ah lead acid battery, 8051 microcontroller, PIR sensor, ultrasound and adjustable stand. As per design calculations the system was fabricated in the Renewable Energy Practical Lab. The performance of solar powered ultrasonic system installed in Soybean Field, Dept. of Agronomy, Dr. PDKV Akola was evaluated for repelling the birds and animals. The average values of ambient temperature, wind velocity, panel temperature, solar intensity, panel output, panel efficiency, panel voltage, panel current, exergy efficiency of panel and battery voltage were recorded. It was observed that the panel voltage increased with the increase in solar intensity. Similarly the battery voltage increased with respect to the solar intensity. At 9.00 h solar intensity was found to be 248.1 W/m2 and the ambient temperature, wind speed, panel voltage and battery voltage were found to be 31.4 0C, 1.69 m/s, 17.5 V and 10 V respectively. At 17.00 h solar intensity was found to be 236.3 W/m2 and the ambient temperature, wind speed, panel voltage and battery voltage were found to be 31.9 0C, 1.76 m/s, 17.6 V and 13.9 V respectively. The peak solar intensity was found to be 831.6 W/m2 at 13.00 h and the corresponding ambient temperature observed was 36.7 0C. Also the peak panel voltage was found to be 21.8 V and the corresponding panel current and battery voltage observed was 0.59 A and 13.2 V at the time of 13.00 h. The battery was fully charged within 8 hours at the voltage of 13.9 V at the time of 16.00 h. This study was carried out to see the feasibility of using Passive Infrared Sensor (PIR) to protect crops from birds and animals. PIR sensors are motion detector sensors and operates based on the infrared radiation from the body. The sensor has the advantage of low cost, and it is used extensively in indoor automated motion detection systems. All bodies including human emit infrared radiation and the radiation amount depends on body surface temperature. The proposed system consists of a microcontroller, frequency adjuster, sensitivity adjuster, an ultrasound comprising of a lighting. When the birds or animals were in the range of PIR sensor it senses the motion and it gives signal to the microcontroller which gives signal to the ultrasound and ultrasound starts vibrating. The estimated cost of the system was Rs 5600 /- with a payback period 2 years 6 months and benefit cost ratio was found as 1.57. It could be inferred that the solar powered ultrasonic system was technically as well as economically feasible.
