Green stuff poured on pcb withing plastic box .I dont know that green stuff and which cover all electronic component. Only connector cables and power supply cable is available.
The green stuff like a gel or jelly.
So , what is this green stuff ?
Thank you.
If required , I can take a photo...
Yes , I solved problems which were we faced.The problem is battery life and ultra low power sensor.... :) I will try to contact distributors for ultra low power sensor.
I saw a system which was working with hall effect sensor and was supplied by battery and system seem to me long lasting ( +5 years ) , that means their system consumes at small currents .May be at uA levels instead of mA.
Guess about it , I cant figure out...Thank you!
A new question , This project is battery supplied and battery is 20000 mAh.
According to datasheet in Electrical Characteristics table that supply current Idd = 3.2 mA .
Is that 3.2mA that sensor consume while it works? If it is , then battery can supply for 20000/(3.2*24) ~= 260 days .
Is my...
Friend as you see in the datasheet page 8 , in the table output Voltage you cant see 3 volt or 4 volt on sensor output ;
VOL Output Voltage 130 280 mV
As I showed above , I read ~300 mV when there is no magnet close to sensor, when you put magnet close to sensor , output become 0V .
So as I...
Hi Dears,
I have a hall effect sensor 506 you can check it here http://pdf.datasheetcatalog.com/datasheet/MicronasIntermetall/mXuxyww.pdf
I made basic connection . it has 3 pins .
1-> VDD
2-> GND
3->Output
İt is working it gives 0.3 V normally . When I keep magnet close to sensor outpot...
Questing was -> I want to measure How much battery supply exist? My microcontroller unit will wake up 2 times in a day and it will work for 10 second and then it will be in sleep mode.
Now I want to know my battery state for 3 years later.I want to show battery status on display.
Now I have...
You should use something like encoder and you can use stm8s discovery kit which is really cheap eval board it has a lots of example. On the other hand TI launchpad msp430 based eval board is capable to do it.
