General Characteristics of the SDI-12 channel:
- Multiple SDI-12 sensors can be attached to the Wildeye SDI-12 "master".
- All sensors will be simultaneously powered up by the Wildeye 12V SPO when it is time to read from the sensor
- The 12V SPO can supply a maximum of 150mA at 12V to all attached sensors.
- Care must be taken to ensure that the total power draw from all attached sensors (including non-SDI12 sensors) does not exceed the maximum capacity of the Wildeye 12V SPO, otherwise it may cause sensors to fail to read correctly.
- Each attached SDI-12 sensors has an address in the range from 0 to 128, according to the SDI-12 standard.
- The default SDI-12 address is typically "0". If multiple sensors are connected, they must be set to different addresses otherwise they will conflict and the Wildeye will not be able to read them.
- SDI-12 communication is digital UART communication at 1200 baud.
- SDI-12 sensors can provide multiple parameters with each read.
Setting up an SDI12 sensor on your Wildeye is simple:
- Check to see if your sensor has built-in support with the Wildeye EasyConfig tool. If your sensor is already supported, it is a simple case of choosing the sensor and selecting the SDI-12 address.
- If the sensor is not supported via EasyConfig, you can build your SDI-12 sensor setup using standard SDI-12 commands. For further details see here.
