OPERATION AND MEASUREMENT

Connect the sensor to a measurement device (meter, datalogger, controller) capable of measuring and displaying or

recording a voltage signal with a range of 0-2.5 V (SQ-212/222) or 0-5 V (SQ-215/225) to cover the entire range of PPFD from

the sun. In order to maximize the measurement resolution and signal-to-noise ratio, the signal input range of the

measurement device should closely match the output range of the quantum sensors. The amplification circuit requires a

power supply of 2.5-24 VDC (SQ-212/222) or 5-24 VDC (SQ-215/225). NOTE: To prevent sensor damage,

sensor to a power source greater than 24 VDC.

VERY IMPORTANT:

Apogee changed all wiring colors of our bare-lead sensors in March 2018 in conjunction

with the release of inline cable connectors on some sensors. To ensure proper connection to your data device,

please note your serial number or if your sensor has a stainless-steel connector 30 cm from the sensor head then

use the appropriate wiring configuration below.
