No more AC power needed or batteries to replace! The photovoltaic module in the LEIT-2 harnesses light energy to generate electricity that is stored and used to power the controller day and night in any kind of weather. In a normal day with direct sunlight, an average of 100,000-130,000 lux can be measured. The LEIT-2 controller only requires an average of 3,000 lux for a normal operation. Light illumination is measured in terms of lux (lx) or foot-candles (fc). A lux is equal to the total intensity of light that falls on a 3.5 square feet (one square meter) surface that is one foot away from the point source of light.
Designed and engineered with the environment in mind. Creating a product that can use less energy and can be disposed of easily without adverse effects on the environment. The electronic assembly and components are certified lead free. The controller does not use a battery to store power; as a result, various toxic pollutions from lead are prevented. In addition, the controller is mounted directly or close to the valve all but eliminating the needs for long copper wires. Another environmental benefi t of the LEIT-2 controller is that it utilizes solar technology to collect ambient light to power the controller. Ambient light is natural light, or available light. LEIT-2 has been engineered to use energy so efficiently that only ambient light is needed to power the controller day and night in any kind of weather, anywhere in the world.
The goal of the LEIT-2 system is to provide wireless irrigation control technology in a handheld remote that has the functions to support all the user needs. Once the LEIT-2 controller is installed there is no further reason to visit the controller because all programming, testing, and operations are conducted using the handset. Communication range between the handset and the controller can be established from up to 350' line of site. The handset communicates with the controllers using 2-way communication; after receiving the data the controller send confirmation back to the handset verifying successful transmission. The handset stores the addresses of the last 10 controllers it visited, enabling the user to easily reconnect with controllers on the grid.
