Agricultural Light Sensor Details
Light, temperature and moisture are the 3 most critical parameters for plant growth. With the LT150 you'll be able to determine if your plants are getting enough light, or too much light. When used with our VegeHub you'll be able to track seasonal light patterns on your computer or phone's web browser over time.
The LT150 has a very large light range of up to 150,000 lux. As a comparison the maximum light on a bright day on the earth is 120 KLux, so the sensor will work for any outside agricultural application, or inside to detect the light levels of grow lights.
How it Works
The heart of the sensor is a diode based light sensor. This diode mimics the response of the human eye, with a peak sensitivity at 540 nm and spectral bandwidth ranging from 430 to 610 nm. The signal from the sensor is amplified and processed by a tiny but powerful microcomputer. The diode sensor has a wide angle of sensitivity (+/- 60°), so even if it isn't directly pointing at the sun it will still accurately detect light levels for your plants.
Easily Mountable
We've put a lot of thought into the enclosure design to make it easy to deploy. It includes a PVC adapter which allows it to mount to the end of 1/2" PVC tubing. You can pound the tubing into the ground, and then secure the sensor to the end with a screw. The altitude angle is adjustable with a single set screw. If you want to mount on a flat surface rather than PVC, you can discard the PVC adapter, and mount it directly to a flat surface.
If you would like to mount it to a different diameter of PVC contact us to see if we can design a special adapter for you.
Waterproof and Rugged
The enclosure is waterproof with a gasket, and potting at the cable entry point.
Low Power
The LT400 is very low power consuming only about 2mA (6mW). If used with our Voltage to 4-20mA Current Loop Translators it can be turned into a 4-20mA current loop powered sensor.
Interface Our Sensors to any System
The LT150 will easily interface to any decent data logger, or microcontroller. It uses a simple analog 3 wire interface (VCC, GND, VOUT). Customers have connected it to Arduino boards, electron particle IO boards, and a slew of common microcontrollers. The output ranges from 0 to 3V so any system that can read a voltage can interface to it. For evaluation use a common volt meter to read its output, and determine the light level.
Vegetronix Agricultural Building Blocks
We provide modular building blocks that you need to create your agriculture application. With these building blocks, you can create systems that will monitor light levels and control lights and valves based on the readings.
For recording data, we carrier simple low-cost data loggers, which can read up to 8 sensors. Waterproof wall mountable displays allow you to see your sensor data, near its source.
For remote viewing of data, we provide a WiFi Data Logger, which will read up to 4 sensors, and store data in the cloud. This Sensor Hub lets you remotely view your sensor data on your phone's web browser. You can even receive text messages, and email alerts.
We've partnered with the sensor cloud site - VegeCloud.com which will graph, store, and manage your light level data.
