VoltRadar is a wearable high-voltage proximity alert device from Jarsh Safety, built for anyone who works near live electrical equipment. It detects high-voltage proximity on a dielectric harness and warns the wearer immediately with a buzzer, a vibration motor, and status LEDs — before contact becomes a risk.

The VoltRadar Companion app connects to your VoltRadar unit over Bluetooth Low Energy (BLE) and turns your phone into a live dashboard, configuration console, and history log for the device.

WHAT YOU CAN DO
• Live Dashboard — see the device's real-time high-voltage sensor trace, connection status, and Smart Pause control the moment you connect.
• Alerts, your way — high-voltage detection triggers a buzzer, vibration motor, and red status LED on the device; use Smart Pause to silence buzzer and motor mid-alert without losing the visual warning.
• Battery monitoring — track charge level at a glance, with low-battery alerts before the unit needs a recharge.
• Calibration — set the high-voltage detection threshold to match your working environment.
• Device configuration — tune buzzer and vibration timing, startup self-check duration, battery thresholds, and more, then push the settings straight to the device over BLE.
• History and trends — review whole-day and per-session high-voltage exposure charts, so you can see when and how often alerts occurred.
• Role-based access — User, Supervisor, Sales, Production Team, and Developer roles, each with PIN-protected access appropriate to the job, so calibration and configuration stay in the right hands.
• Bench tools — a USB serial terminal for provisioning and testing VoltRadar units on the bench.

BUILT FOR THE FIELD
VoltRadar is designed for electrical linemen, utility crews, industrial maintenance teams, and anyone else whose job puts them near energized equipment. The device runs independently on its own firmware — the app is there when you need to check status, calibrate, configure, or review history, and stays out of the way otherwise.

ABOUT JARSH SAFETY
Jarsh Safety (Jarsh Innovations Pvt Ltd) designs IoT-enabled industrial safety equipment focused on one goal: safety, the smarter way. VoltRadar is part of a growing line of smart safety tools built to protect people doing demanding, high-risk work.

Requires a VoltRadar hardware unit, sold separately. Bluetooth and location permissions are used only to scan for and connect to your VoltRadar device over BLE.
