IoT4H2O - Universal data collection with IoT

IoT4H2O^® („IoT for water”) are small, low-cost data acquisition, actor- and transmission devices that communicate via LoRaWAN or NB IoT wireless standards and can be equipped with a variety of different sensors.

IoT stands for Internet of Things. IoT data acquisition systems transmit the acquired measurement values via radio and make the data available in a data cloud.

The IoT4H2O^® devices thus enable both, the inexpensive new construction of wireless data acquisition systems and the upgrade of existing sensors with wireless data transmission capabilities, thus bringing the company's own data acquisition to a new level. Outdated handheld readers or data loggers without wireless data transmission can be replaced while continuing to use existing sensors. In this way, resources are saved.

The IoT4H2O^® devices use the IoT narrow band standards LoRaWAN and NB IoT. These radio standards are characterized by extremely low power consumption, low costs, high range, data security and an unprecedented penetration of obstacles, and are therefore ideally adapted to the requirements of data acquisition in agriculture and horticulture and generally in the outdoor area.

Summary:

What is IoT for water?

• IoT4H2O^® is a universal data acquisition and actuator system

Which IoT4H2O^® devices are available?

• IoT4H2O^® data acquisition devices
• Act4H2O^® actuator devices

How does IoT4H2O^® transmit the data?

• Data transmission either with NB IoT or with LoraWAN radio

Typical applications

• Data acquisition in agriculture
• Data acquisition in horticulture
• Data collection in urban green spaces and in an urban context
• Data acquisition in landscaping
• Data acquisition in research and development
• Data collection in renaturation and nature conservation
• Data acquisition in water management

How is the data provided?

• On our WebApp www.IoT4water.de for smartphone and computer
• Via API
• Via UDP forward (for NB IoT devices, for developing your own data interface)
• Via HTTP callback (for NB IoT devices, for developing your own data interface)
• Own Lora infrastructure (for Lora devices, for the development of an own data interface)
• Payload decoder available

What can IoT4H2O^® measure?

• Soil water potential
• Soil / substrate water content
• EC value of the soil solution
• pH value of the soil
• Air temperature, soil temperature, water temperature, wet bulb temperature, etc.
• Rel. humidity
• Radiation: Global radiation, PAR, UV
• Precipitation
• Dendrometer
• Water level
• Duration of leaf wetness
• Air pressure
• Water meter (also the BayWa low-cost water meter art. no. 1987923)

See separate sheet for list of sensors currently supported by www.IoT4water.de

Furthermore, in principle, any sensor with a volt signal or resistance signal or SDI-12 communication can be detected by IoT4H2O devices, provided that the required supply voltage of the sensor does not exceed 5 V DC.

The raw value can also be recorded and displayed to create your own calibrations (e.g. creation of soil or substrate-specific calibrations for water content measurement).

Which and how many sensors can be connected to a device?

• IoT4H2O^® devices:

  • Up to 6 sensors with resistance signal and up to 3 sensors with volt signal or
  • Up to 10 sensors with SDI-12 communication as a sensor bus chain

• Act4H2O^® devices:

  • 1 rain gauge, 1 water meter
  • 1 switching output for valves with continuous current coil
  • 1 switching output for valves with pulse solenoid coil

How long does a set of batteries last?

One set of batteries provides 10,000 to 12,000 transmissions. The transmission interval is infinitely adjustable between every 3 minutes and every 720 minutes.

This means:

The table values apply to sensors with lower power requirements. Resistance sensors have a lower power requirement than volt sensors. SDI sensors have a rather high power requirement.
