摘要:
Some embodiments provide irrigation valve control apparatuses comprising: multiple terminals coupled with a multi-wire path; a first charge storage circuitry electrically coupled with at least one of the multiple terminals, wherein the first charge storage circuitry is configured to be charged by a voltage on the multi-wire path; a control circuitry configured to determine the voltage on the multi-wire path; and a boost circuitry controlled by the control circuitry, wherein the control circuitry in response to determining that the voltage on the multi-wire path is below a threshold activates the boost circuitry to increase a voltage stored by the first charge storage circuitry.
