Hi everybody! Just finished with my new little gadget and feel like sharing with LMR. :)
The gadget is room temperature monitor for our baby we are waiting to have this month :)
What it is intended to do:
monitor room temperarure
"backlight" to be used in the night
vibro and light alarm on temperarure out of range
Here are my parts:
My favorite enclosure: small food container :)))
Picaxe 08M chip
CHI040 project board
Vibro motor ripped off old thoothbrush
LED
Push button
Micro servo
Battery holder
BC548B NPN Transistor
DS18B20 digital temperature sensor
A couple of resistors
Building in progress:
Ready product: :)
Operation is really simple: It reads temperature from sensor, updates servo powered dial, then checks if temperature is in range of 16-24 C. If not, vibro and light alarm goes off.
I hope this thingey is going to be usefull :) Looking forwart to "field" tests :D
Add a cheap RF Transmitter and microphone and have it send a signal to some pager if the temperature is out of range or there is some loud noise (crying) !
You will also want to invent something to make the kid sleep
