The original design is maybe 15yrs old & uses a ATTINY. I'd obviously use a more modern nano power MCU for harvested energy. |

The ATTINY should be OK lasting years on a CR2032, modern MCU may be slightly better. I would work on the code and stick with CR2032. Or maybe a rechargeable CR2032 equivalent and a small solar cell. |

--- Quote from: Mark Ruiz on January 19, 2023, 09:39:22 pm ---These types of buttons are commonly called "reed switch buttons" or "magnetically actuated switch buttons". They are typically used for low-power, wireless applications such as remote controls or smart home devices. Some well-known manufacturers of reed switch buttons include Honeywell, Omron, and NXP. These companies offer a wide range of products, including buttons with different form factors, snap action types, and power ratings. You can also find reed switch buttons from other reputable manufacturers such as Panasonic, TE Connectivity, and Alps Electric. --- End quote --- Hmmm... Bot much? |

I was worried that someone even more newbie in electronics than I am would mistakenly believe that we're talking about reed switches here. We're not; the switches discussed here harvest the energy from the button push to power the circuit itself for a very short moment, just enough to transmit a RF signal packet. |
