The unit shall permit remote configuration, realtime monitoring and operation of all field devices through a secured cloud platform, supporting user-defined control logic based on timed sequences, automated schedules, and conditional rules. Output relays shall be of heavy-duty industrial grade for extended service life. Communication ports shall comprise: (I) Modbus RTU/RS485 input for field instruments including pressure sensors, level transmitters, flow meters and temperature sensors; (II) Modbus output for BMS/SCADA connectivity; (III) One 4–20 mA analog input; (IV) In-built LoRa wireless receiver at 865–868 MHz for long-range sensor data reception; (V) Integrated GSM/4G IoT SIM module for cloud connectivity enabling real-time data push, remote diagnostics and configuration via web or mobile. Onboard LED/LCD display (min. 2.8 inch) shall show device status, communication health, sensor values, alarms, relay states and diagnostics. Housing: polycarbonate, IP65 rated including proper fixing and connection etc. complete as required

Supply, Installation, Testing and Commissioning of a battery-powered laser-based water level sensor with integrated wireless transmitter, for measuring water level in dewatering pits/STP tanks/water tanks and wirelessly transmitting the reading to a remote controller or display unit. The transmitter shall operate on the 865–868 MHz ISM band with minimum RF output of 15 dBm and IP68 ingress protection rating for continuous submersion service. Level data shall be transmitted as a percentage value (0–100%) to the paired receiver unit. Maximum sensing depth: 8.00 metres. Complete as required.

SITC of a high-precision digital pressure sensor intended for reliable monitoring of liquid or gas pressure in industrial and automation enviroments. The sensor shall provide accurate measurement over an operating range of 0-30 bar (Absolute pressure) and shall function within an ambient temperature range of -22C to 85C, ensuring suitability for water management systems, pumping stations, and building automation applications. The device shall facilitate early prediction of pump priming failures and foot-valve chokage. Output communication shall be via Modbus protocol, enabling seamless interfacing with controllers, data loggers, SCADA systems, and Building management Systems (BMS) for remote monitoring and diagnostics. The sensor assembly shall include a 50 cm PU2 tubing of 4 mm outer diameter compatible witrh standard push-in fittngs, terminating in an M4 male connector for secure mechanical connection to the pressure port.

Providing access to a web-based platform for remote water level monitoring and automated control of the dewatering pump/motor system, hosted on a Tier-III certified data centre located in India. The platform shall present live operational parameters through a graphical dashboard supporting historical trend viewing and data export in CSV and graphical formats. Tank threshold limits and motor sequencing, scheduling and control logic shall be remotely configurable via web browser with multi-level user authentication. Automated WhatsApp alert notifications shall be dispatched to multiple designated contacts upon level limit violations, foot-valve chokage or pump priming failures. Subscription covers server and application access for one Motor Controller / Valve Controller for 12 months; hardware billed separately. Complete as required

Supply , Installation, Testing and commissioning of 230Vac/5V DC operated RF signal booster/repeater operating in Frequency band 865~868MHz confirming to EN.300.220 to relay/transmit the RF signal received from multiple transmitters to further distance with LED-based instant indicator. It should have a technique to avoid collision of RF signals and minimise corruption of data. A mechanism should be there to avoid circular transmission of data between booster/repeaters. LED-based visual indication should be there to indicate the signal strength of received wireless data. It should have RF receiving sensitivity of minimum -125dBm and transmission power of minimum 15dBm. It should be configurable to filter out RF signals of particular transmitters to reduce the transmission signals in the air. It should have a shock-proof ABS body with IP65 rating and must have suitable mounting arrangements on wall or stand, etc., complete as required
