But i use bridge rectifier, so peak to peak only Vrms * sqrt(2). I used oscilloscope to show wave on display. ACPL-C87 have Input Impedance about 1GOhm (very large). The problem only happen when power up ACPL-C87.
The schematic like below
I don't have LR8, so i use 5V from kit STM32F1 to supply...
Hi, I have some problem with ACPL-C87 ().
I intend use ACPL-C87 for measuring voltage with scheme like this
AC (220V/50Hz) --> Bridge rectity --> resistive divider (R1 = 1.5 MOhm + R2 = 10 kOhm) --> ACPL-C87.
Based on datasheet of ACPL-C87, I use resitor 10 kOhm. Voltage on R2 about 2V peak to...
I use C18 compiler. I have some problem:
1. I2C debugger notice: error
2. Can't write ds1307

I have some pictures of this sensor. But i don't know what its name is
i will recheck deep in the sea bottom that i want to measure
=======
Thank a lot
I want to find sensor that is used to measure depth of sea. But i found but i often receive short distance sensor. Can you recommend me some type of sensor to measure depth of sea?
Thank a lot.
I have a fail machine named furuno fe-6300 using to measure depth. I don't know what the sensor is used. So that, i hope in forum has somebody know this sensor to give me advise. I intend use Microcontroller to measure
Thank a lot.
