Hello Everyone,
I want to let everyone know that I do not have any Arrival Sensor from the last batch. I have started to look into making improvements for a new butch in the event that I will make a new batch.
During this process of making a revision, I found an unfortunate error on the battery protection wiring on the current batch. Although the sensor is fully functional, the battery protection is important to make sure that the battery is used properly. There is a risk of damage to the battery during usage. Using damaged battery could cause fatal accident. I have not heard any issue on the field at this point. However, I want to make sure that I disclose the issue so that everyone can take action. If you decided not to use the sensor as one of the solution, I would be happy to refund your payment for the cost of the sensor. Please send me an PM.
I will correct this error if I decided to run a new batch. I have not committed to make a new batch at this moment.
I am aware that from the feedback that some of us including myself is excited about the sensor and its potential. It would have been a painful to loose the functionality. Again, I offer to refund your cost of the sensor if you decided not to use it. But, If you sill want to continue to use the sensor, to minimize the risk, you can use a protected battery. A protected battery contain the protection circuity in the battery itself. This configuration is not something that I have designed for. I cannot for sure that it will eliminate any risk with this configuration. If you like to have more information, please feel free to PM me.
I am just a like a hobbyist who want to make improvement to our smart home. I make some sensor to share with the community because I feel that it would improve our experience. I would like to apologize for this unintentional mistake.
Thanks
Iman
