Try to avoid direct use in the following environment: salt mist, corrosive gas: strong acid (sulfuric acid, hydrochloric acid), strong alkali, organic solvent (alcohol, acetone, etc.).2. Recommended storage conditions: temperature 10oC-40oC, humidity 20%RH-60%RH.3. It is recommended to use manual welding instead of wave soldering and reflow soldering. The welding temperature should not be too high and the welding time should be within 12 seconds.4. Due to the difference in the temperature of the welding or storage environment, it will have an impact on the field test results. It is recommended that the residual temperature of the module be eliminated 2 hours after welding or 30 minutes after leaving the storage environment, the temperature and humidity measurement be carried out after reaching the balance with the environment to ensure the accuracy of the measurement.5. On the premise of selecting a communication format, ensure that the design, wiring and jumper are carried out according to the electrical parameters, circuit diagrams and jumper methods recommended in this specification, and use them according to the specified software protocol or reference routines.6. In special circumstances, such as high temperature and humidity, it is necessary to stick waterproof and breathable film or built-in waterproof and breathable film on the shell to protect sensitive devices before measuring.Pin description:1.VDD power(2.7vdc-5.5vdc)2.SDA Bidirectional serial data3.GND Ground4.SLC Serial clock input port(Grounding in case of single bus)Application circuit recommendationsThe module CHTA30IW has two communication modes at the same time:1.
