Firmware-62 Command-111

In host mode or stand alone mode the host can send a request to the Wi-microDig to get the low power level status. This feature is useful to get the status of the voltage at the sensor input connector. A low power level status would mean that the inputs are no longer at 5V. Some sensors can only work at 5V, so the output for these sensors would not be valid when the low power level status would be active. When sending the LOW POWER LEVEL command the Wi-microDig will respond with a "normal level" reply (F0h 7Dh 00h 6Fh 00h F7h) if the battery voltage level is higher than 5.2V (+/- 0.1v). However, if the battery input voltage level is below 5.2V (+/- 0.1V) then the "low voltage level" message will be replied (F0h 7Dh 00h 6Fh 01h F7h).

The Wi-microDig can work at voltage levels down to 3V. Below this voltage level the communication between the Wi-microDig and the host computer might be disrupted. Note that the RED power LED will flash if the voltage level on the battery is below 5.2V (+/- 0.1V) but the Wi-microDig will work at voltage levels down to 3V.

There is no [BODY] for the LOW POWER LEVEL command.

Example:

240, 125, 0 {DEV}, 111 {POWER LEVEL}, 247 (F0h, 7Dh, 00h, 6Fh, F7h)
