Hi !In caseConnect live wire from AC wall outlet to Common port on relay and one terminal of AC bulb to Normally open terminal of Relay.Then, Connect the other terminal of AC bulb to GND on the AC wall outlet.However, my relay module will operate with LOW signal and PIR is operating at HIGH signal. Therefore, when I connect one terminal to Normally Open. It doesn't work. And then change Normally Open to Normally Close => It operates normally. Is it OK with that??? Thank youP/s: Sometimes, all system doesn't work correctly like Lamp still turns off permanently. Any suggestion?
I think that we can have another solution for this by buying good cells and replacing into the case :))
I think probably many parts or components of electric device are made from China. But I highly recommend that we should not buy products with unfamiliar brands, low price, no warranty that comes from China. I agree that Xiaomi is a good and big company which supplies many useful products. However, there are numerous companies that they are making largely range of fake products. We should be aware of that. On the other hand, we can use various electric devices with global brand such as LG, Samsung, Electrolux, Sanyo, Sony.. These are made from Korea or Japan or even Hong Kong.
I think we probably must be careful with products made from China.
