DEMÉTER 1H Remote control hardware

Deméter is an IoT device made by Hidroconta to control hydraulic equipment such as hydraulic valves and water meters and sensors on water distribution systems.



Deméter 1H

The Demeter is a latest generation wireless GRPS-Radio remote control system and supervision of different equipment and facilities related to water consumption and distribution. Completely developed by Hidroconta, the system allows, among other advantages, the digitization of hydraulic networks in a simple way and reducing the cost of deployment.


Communications tailored to the system’s topology

Deméter 1H communicates with a central server using GPRS technology or free-band radio and it can operate continuously for 6 months with no communications without losing any information.

Self-contained device

Deméter, Hidroconta’s remote control device, is a fully autonomous system. Powered by a single lithium battery that provides a battery life greater than 3 years for the GPRS version and 10 years for the RADIO version (24 communications per day).

Asset control

The Deméter 1H device is able to control one hydrant (water meter plus hydraulic valve) and a digital input.

Dual functionality

This hardware developed by Hidroconta can function as a GPRS end-point

Meter input

Designed for reed-type potential free contacts. 30 uA consumption with a closed contact. It can also be used with open collector-type pulse emitters (respecting the polarity).

Digital input

Potential free contact. Similar to that described for the meter inputs. Useful when used with intrusion detection systems, digital pressure switches, etc.

Analogue inputs

  • 2 10-bit resolution 0-20 / 4-20 mA analogue inputs.
  • The device has a 15 Vdc terminal to power the sensors.

Solenoid valve outputs

Deméter 1H has 1 output for a 12 V latching solenoid valve. Triggering is performed using the energy stored in a 4700 uF capacitor charged to a voltage of 18 V. More than sufficient for most manufacturers.


  • Deméter 1H is operated by a microcontroller with 256 KB of storage for firmware and 96 KB of volatile memory for program data.
  • It also has external non-volatile memory with 244 KB to store records and settings. Enough to store over 20,000 records.
