Electric shocks due to high voltage lines can pose serious health risks to workers. Reliable and efficient systems to alert workers of nearby live power lines are necessary. In this paper, a personal high voltage safety system with wear monitoring is designed and implemented. A wrist module which consists of an electric field detector and optical heart rate monitor is developed from first principles. The complete system allows the heart rate of a subject to be monitored and reported wirelessly to a GSM/GPS enabled module placed on a vehicle. The system can operate reliably in an area with high electromagnetic fields.
