4. Standard test condition
1) Testing condition: normal temperature:25℃, voltage:5V
Put temperature and humidity module in 20%RH below humidity environment for 30 minutes. Then put
it in testing humidity environment for 15 minutes to test module voltage.
2) Testing instrument
--Humidity generator: high-accuracy, constant temperature an humidity test chamber: Cheng FU.
--Standard: photoelectric point hygrometer of GE Company
-- Voltage
5. Reliability Test
No, Item, Way, Requirement
1) Impact test: make the sensor fall free form one meter height to hard wood flooring three times. If the sensor is without be broken or destroy, the electrical property is ok.
2) Vibrating test: vibrating in X-Y-Z axis for 30 seconds, Frequency with 10-55 HZ, Range: 1.5mm, If the module is without being broken or destroy, the electrical property is ok.
3) Heating test: put the sensor in constant temperature 55℃ and humidity 3%RH for 1000 hours, accuracy：±5%RH.
4) High humidity: put the sensor in temperature 40 ℃ and humidity 95% for 1000 hours, accuracy: ±5%RH
5) Temperature test circularly: 300 times circulation. Put in -10 ℃ for 1 hour per circulation; then up to
55 ℃ and put for 1 hour; Then continue another one circulation. accuracy：±5%RH/±0.5℃.
Remarks:
1) All data are based on the temperature and humidity changing range: with 80%RH
2) After each test, the module should be put in normal environmental temperature and humidity for 24 hours and then continue another test.
6. Package
1）20pcs module per box.
2）Parameter list.
3）Bulk package. Style available
4）Plastic case available.
7. Remarks
1）Should not connect DC to sensitive component directly.
2）Should not put component in condensation and dry environment and below for long time.
A. Salt-fog B, acidic or oxidizing gases, such as sulfur dioxide, hydrochloric acid, etc.
3）Because sensitive capacitance is PF, humicap capacity should not be welded off PCB and then down-lead welded. Or it will lead to humidity value shift
4) Should not put in water to test. Or it will destroy sensor
