EnOcean, world leader in energy harvesting wireless technology, offers a maintenance-free low power, long-range wireless system for the Japanese market based on energy harvesting technology for multiple outdoor solutions, such as agricultural, water level and environmental monitoring under its Dolphin brand. The sensors in these types of applications need to be protected from extreme weather conditions. Therefore the energy harvesting long-range system has been designed with a robust weather resistant cast aluminum housing for the self-powered wireless sensor transceiver (EMOS 200LH) and gateway transceiver (EMOT 200LH). Additionally the long-range wireless solution includes eight sensors with generic interfaces, allowing new sensors to be added to the system flexibly later on without requiring software updates.

EnOcean´s energy harvesting long-range wireless sensor solution is being used in the agricultural field, where there are heavy rain showers, freezing conditions, strong winds and sunlight. Apart from using it in the agricultural field, it can also be used for monitoring buildings and bridges that are exposed to rain and sea water directly, water level monitoring in rivers and shores, measuring temperature and flow rate in chemical plants and tanks, managing entrance and exit to parking lots, as well as various ocean applications for measuring distance and water temperature.

Self-powered wireless long-range sensor system for outdoor environmental monitoring

EMOS 200LH and EMOT 200LH with weather resistant aluminum casting housing

The EMOS 200LH sensor transceiver is encased in a robust and weather proof housing with three M16 interfaces. Two interfaces are used for connecting external sensors, while the third permits the individual configuration and software updates. An integrated solar cell allows for fully maintenance-free operation and facilitates the collection and transmission of data within a defined period of time over several kilometers. The EMOT 200LH gateway transceiver uses the same housing but without a solar cell window, since the latter is supplied via its own interface. This interface also makes it possible to transfer the data to the cloud.

EMOS 200LH and EMOT 200LH can be used for over 10 years without having to worry thanks to their water resistance and sturdy materials. The aluminum housing is heat- and water-proof, resistant to humidity and sunlight and also provides dust resistance.

Increasing the sensor portfolio

In addition to the sensor transceiver and gateway transceiver, the long-range wireless solution from EnOcean includes eight different sensors with generic interfaces, including a temperature and humidity sensor (ESO-A), a soil moisture sensor (ESO-H), a soil temperature sensor (ESO-T) and an illumination sensor (ESO-I). Now, further sensors such as an occupancy sensor (ESO-O), a distance sensor (ESO-P), a food sack temperature sensor (ESO-R) as well as a barrel temperature sensor (ESO-S) complete the system. All sensors are connected to EMOS 200LH via short cables with robust outdoor plugs. A generic interface was developed for this purpose, which enables new sensors to be added to the system flexibly later on without requiring software updates in EMOS 200LH. The system will be completed with further sensors like a CO2 sensor for use in greenhouses as well as a tilt sensor for infrastructure applications, which are currently both in field trial.

Energy harvesting solution for environmental monitoring successfully being used in Japan

EnOcean energy harvesting long-range wireless sensor solution has been installed from Hokkaido to Okinawa and in various other places within Japan, such as Fukushima. Since 2013, NTT East, one of Japan´s leading telecom operators, started field tests in open fields and greenhouses all over Japan to test that EnOcean´s long-range wireless system can withstand many years of very high or low temperatures, high humidity levels, high levels of sunlight in the south, typhoons, strong rains, damage caused by seawater as well as spraying of agricultural pesticides and dung. The EnOcean energy harvesting long-range wireless sensor solution was extensively tested and proved to be a very reliable, high-quality product. Additionally, during these field tests, the sensor system showed significant cost reductions. NTT East has already started to supply their end-users a wireless solution for environmental monitoring based on energy harvesting technology.
