As part of an IT project, I am responsible to acquire data from a hive. (Weight, Temperature and battery voltage)
In fact I have an electronic scale with sensors (Weight, Temperature, Voltage) connected in conjunction I2c to my FEZ Panda II card that is connected via USB to the PC.
I’m not sure where to start, how to do really take and is it they are people who have already worked with such equipment, to make a very similar work.
sounds an interesting project. I doubt anyone has an identical project, but you may find similarities and helpful pointers.
For starters, if you’re looking for tips, you might want to describe what the scale/sensor platform you’re using is (part numbers if possible, data sheet at a minimum) so others who are interested to help have some idea what you’re looking at. Beyond that, I’d also suggest you describe what you want to achieve - do you mean a beehive, sitting in a field somewhere? Does the Panda have to sit permanently with the hive ? Do you have power ? How do you expect to get the data to “home base” ? Thinking through these things and describing them here will mean any help we can give starts to become relevant, otherwise we could be randomly taking you in the wrong direction.
Whats the make and model of your scale? Add a link to the user manual. You would also probably want a GPRS module to get data when the hive is full to collect.
Actually, I have an electronic hive hive making office. The idea is to get something sensors, that is to say, slave i2c component. My FEZ Panda II calculator is the master and I2C components are the slaves, the master must poll the i2c component (Slave) which has its own address that it responds to obtain information.
I don’t have user manual… And no GPRS module. JI just want to get the temperature measured by the panda calculator.
Master slave principle between the panda and I2C comosants
step 1: refer to https://www.ghielectronics.com/docs/12/i2c to see how to check the return of the i2c Execute() call. You don’t know if it is communicating to the chip or not.
step 2: tell us about your A0/A1/A2 lines and how they’re set.
