Frequently Asked Questions
Clear, direct answers regarding our industrial IoT engineering capabilities, water quality telemetry, 3-phase power monitoring, custom PCB design, and manufacturing from Visakhapatnam, India.
1. What does SK Jalrakshak Innovations (SKJAL) do?
SK Jalrakshak Innovations Private Limited (SKJAL) is an industrial IoT and electronics engineering company headquartered in Visakhapatnam, Andhra Pradesh, India. SKJAL specializes in custom IoT hardware development, embedded firmware (STM32, ESP32, ARM Cortex), multilayer PCB design, turnkey IIoT gateways, online water quality monitoring systems (Jal Rakshak), and industrial 3-phase energy monitoring platforms.
2. Does SKJAL serve clients across India or only in Visakhapatnam?
While headquartered with R&D facilities at Innovation Valley in Visakhapatnam (Vizag), Andhra Pradesh, SKJAL designs, manufactures, and deploys industrial IoT systems, water quality telemetry, and custom electronics for municipal bodies, manufacturing plants, aquaculture operations, and technology startups across India.
3. How does SKJAL's IoT water quality monitoring system work in the field?
SKJAL's water monitoring system operates as an autonomous, solar-powered field station equipped with submerged, anti-corrosive multi-parameter probes. Sensors continuously measure pH, TDS, dissolved oxygen, turbidity, and temperature. An on-board edge microcontroller digitizes signals, applies temperature compensation, and transmits encrypted telemetry over 4G cellular or LoRaWAN to cloud dashboards and SCADA systems.
4. What electrical parameters does the SKJAL industrial energy monitoring system measure?
The industrial energy monitoring system measures 3-phase True-RMS voltage, current via non-intrusive split-core CTs, active/reactive/apparent power (kW, kVAR, kVA), power factor, frequency, and Total Harmonic Distortion (THD up to the 31st order). DIN-rail edge gateways aggregate data over RS-485 Modbus RTU and publish telemetry to cloud consoles over 4G LTE or Ethernet.
5. What custom electronics and PCB design services does SKJAL offer?
Through our custom engineering team, SKJAL provides complete electronics design services from schematic capture to mass manufacturing. Capabilities include 2-layer to 16-layer high-speed, impedance-controlled PCB layout, signal integrity and thermal analysis, component selection, rapid functional prototyping, and Design for Manufacturing (DFM) review.
6. What industrial communication protocols and gateways do you support?
SKJAL engineers custom firmware and turnkey gateways supporting RS-485 Modbus RTU/ASCII, Modbus TCP, CAN 2.0B / CAN-FD, BACnet, and OPC-UA. Uplink connectivity options include 4G LTE Cat-1, NB-IoT, LoRaWAN, and Ethernet with TLS 1.3 encryption and secure MQTT data pipelines.
7. How does the S.H.I.E.L.D. driver safety system protect fleet operators?
S.H.I.E.L.D. monitors commercial vehicle dynamics and cabin ergonomics by measuring continuous whole-body vibration (WBV) acceleration in accordance with ISO 2631-1 guidelines, road shock events, and driving kinematics. It delivers instantaneous in-cabin audible alerts to drivers and transmits telemetry to fleet supervisors to assist in monitoring road vibration severity and occupational ergonomics.
8. How can a business or municipal agency request a quotation or technical discussion?
Enterprises can request an engineering discussion or quotation by emailing sales@skjal.in, calling the engineering desk at +91 89788 59246, or submitting a technical enquiry through our project consultation section. Technical assessments, BOM evaluations, and deployment feasibility reviews are provided within 24 to 48 business hours.
