ambient temperature is 25℃;
Bright resistance: After 2 hours of irradiation with 400-600Lux,
the test value under 10Lux light of standard light source (color
temperature 2854K);
Gamma value: The logarithm of the ratio of the standard
resistance value at 10Lux and 100Lux.
Lg (R10/R100)
Gamma = =Lg(R10/R100)
Lg (100/10)
R10 and R100 are resistance values of 10Lux and

Matters needing attention
1. This product is packed with environmentally friendly materials,
50 pieces of small packaging, 200 pieces of large packaging;
2. Avoid storing the product in humid and high temperature
environment;
3. It should be stored in a non-erosive gas, otherwise it will lead
to oxidation of the tin layer and decrease of weldability.
Therefore, after opening the package should be used as soon as
possible
4. Working environment humidity ≦95%
5. Welding time as short as possible; Soak the tin liquid (Sn63
Pb37) at 230℃ to 5mm away from the CdS photoresistor body, and
maintain 3-5s.
6. Note that the lead welding position should be more than 4mm away
from the ceramic base.
Light Dependent Resistor is a 5mm series photoresistor, 3mm series photoresistor and 7mm series photoresistor that uses the radiant energy from light to control electric current.
