Organic Insect Repellent Vaporizer for Cattle Protection Using Microcontroller

Abstract- Insects adversely affect cattle health, leading to discomfort and disease transmission. This project proposes asmart insect-repellent system that utilizes a microcontroller to control an organic oil vaporizer for effective insect control. Thesystem integrates sensors to monitor key environmental parameters ammonia, VOC, light, humidity and temperaturethat influence insect activity around cattle. The microcontroller processes sensor data and activates the vaporizer for a specific duration based on predefined thresholds. The system employs a nichrome wire heating element a cotton sponge for oil absorption and an exhaust fan for vapour dispersion. The organic oil mixture, consisting of neem oil and fragrant organic flower oil, is used as a natural repellent. By utilizing this chemical-free solution, the system provides an eco-friendly and sustainable method for insect control. This system is particularly suitable for humid environments, such as those found in South India, where insect prevalence is high, offering an automated and cost-effective approach to cattle protection.
