Hello, perhaps, this is wrong section for this, but I dont know, where to ask.
I have 6 pressure sensors, and I would like to make transmitter for each sensor. What kind of connection I have to use ? It will be using PIC microcontroller. Reciever/transimmiter must not affected by others recievers/trasmmiters of course.
You can see, what I mean. Its on the picture.
If you have any ideas, just write it here, thank you very much

a very easy and also cheap ( transmitter/receiver module ~10,- EUR) solution is to use it with
433.92 Mhz modules, with a ready Library of "manchester coding" from mikroC. At this moment i have
a comparable project, have a look at my test construction:
based on AM modulation, it should be transmit "temperature" from some
stations to a host in 1 minutes period. Every measuring station runs with
an simple accumulator (9v block) for transmitter and MCU-system with
a DS-1820 digital temp. sensor.
The consumption of all parts from the measuring station is less than 30mA.
Every measuring station will send the following "data block" every 1 minute:
- controll byte (start 0xaa, 1 byte)
- station number (1 byte)
- digital temperature (1 byte)
- chksum (1 byte)

More suggestions?
so long,

Hi
Consider Decibit's DCBT-24N module based on the nRF24L01 chip....
https://www.plimus.com/jsp/dev_store1.j ... koutOnly=Y
2.4GHz, 1Mps, SPI interface, ACK, low current consumption, though it needs 3.3v it has 5v tolerant inputs, and it has six pipelines for receiving multiple packets. Which can be controlled by a 4550 so you can have USB connectivity.
Depending on certain requirements of the project you wont need 6 receivers.

problem
Hey MasterBlaster i have a problem with thad modules thad you got it. I want to send adc valute via manchester. If i use a wire(direct link) it works. I was joust wondering if u can show me your code and schematic how did you connect transistor to receiver output.
Thanks
Thanks

Re: wireless communication
guys someone pls help me with zigbee communication.
does anyone know how to do zigbee communication using mikroc.
iam new to practical implementation of devices.
so i like to learn..
ur help ill be very interesting to complete my project work..
thank you
