HOBO RH/Temp/Light/External Data Logger
4-Channels: Temperature, Relative Humidity, Light
Intensity and External Input
The HOBO RH/Temp/Light/External has 4-Channels: 1 for temperature, 1 for relativity
humidity, 1 for light intensity and 1 that will accept an external input. It will measure
and record up to 7,943 readings. It's reading rate is user
selectable with sampling intervals being 0.5 seconds to 9 hours,
recording times up to 1 year. Additional features include programmable
start time/date, nonvolatile EEPROM memory which retains data even if
battery fails and an extendable internal temperature sensor.

Light Intensity FAQ's:
Can I use the light sensor on the H08-004-02 logger as an inexpensive light meter?
No! These light intensity loggers are designed to give you a general comparative idea of how much light there is in an area; sunlight v. shade, lights on/off, etc. If you are planning on recording specific lighting information or absolute values, these loggers will not give you accurate data.
Please note that the light sensor on this logger will record from 2 to 600 lumens per sq/ft. Full sunlight is 10,000 lumens per sq/ft. This sensor is intended for indoor light levels only.
The light sensor on the H08-004-02 measures in lumens/sq foot. How does this measurement relate to Lux and Foot-candles?
The two most popular scales for light measurement are Lux, which is the European scale, and Foot-candles which is the U.S. scale.
Lux and Foot-candles are measure of illumination - the amount of light falling on an object per unit area. The difference is whether the light is measured in square meters or square feet:
1 lumens / sq. meter = 1 lux
1 lumens / sq. foot = 1 foot-candles
How can I convert between lux and Foot-candles?
To convert between lux and foot-candles the following factors can be used:
Lux =0.0929 * FC
FC= 10.76 * Lux
Other light sensors are available for the Hobo
Weather Station Data Logger.
