1. A system for use in a wellbore, comprising:
a completion comprising at least one downhole tool, wherein the at least one downhole tool comprises a pilot valve; and
an electronic trigger system comprising:
a longitudinal housing comprising:
a detection section;
an electronics section; and
an actuation section disposed therein;
a pressure sensor disposed in the detection section, wherein the pressure sensor is configured to receive a predetermined pressure signal; and
an electronic control board comprising at least one battery disposed in the electronics section,
wherein the actuation section comprises:
a prefill chamber;
a setting piston disposed in the prefill chamber, wherein a stem portion of the setting piston is coupled to the pilot valve; and
an actuation device,
wherein a predetermined amount of prefilled fluid at hydrostatic pressure is trapped between the setting piston and the actuation device in the prefill chamber;
at least one atmospheric chamber,
wherein the actuation device isolates the prefilled fluid at hydrostatic pressure in the prefill chamber from the at least one atmospheric chamber; and
a pressure port,
wherein actuation occurs when, upon receipt of the predetermined pressure signal by the pressure sensor, the electronic control board transmits power to the actuation device, causing the prefilled fluid to flow through the actuation device and into the at least one atmospheric chamber using the pressure port,
wherein the longitudinal housing of the system is coupled to the at least one downhole tool for actuation of the at least one downhole tool, and
wherein movement of the setting piston triggers an alternate path for pressure through the pilot valve to actuate the at least one downhole tool.
