2023-08-03 – write this email to Paul; decided to make it a blog post for reasons…
Subject: Glucose sensor probably limits communications due to battery life?
Hey!
My guess is the glucose sensors limits communications to alerts only in order to preserve battery life. The little battery in it has to last 2 weeks. It only has 28 mAhr to start with! (contrast that with your Ryobi 2000 mAhr battery pack>
Also, not Bluetooth. It uses NFC (Near Field Communications), yet another way for things to talk to each other.
Other interesting things I learned when looking up the microprocessor in these sensors:
https://www.ti.com/product/RF430FRL152H#features
- Texas Instruments RF430 is a chip specially made for high accuracte (14-bit) analog sensors
- C$6.04 for one, C$3.02/1000 pcs
- Battery is SP636W, 28mAhr
- C$2.39 for one, C$1.35/1000 pcs, C$0.60/5000 pcs.
This really should be a blog post… so it is now!
META: while writing an email to Paul, I over explained (man-splained? nerd-splained?) things. As I do. So I thoguh this would bew better as a blog post, which I can then add to, or refer to , etc. whit good tagging and searching capabilities of a blog like this, this info is now readily avbaialbe to me with two ro three clicks.
