Time is kept during a power failure, and time of day is adjusted upon power up (as long as power is restored within 12 hours). NOTE: The time of day on the main display screen will flash for 5 minutes when there has been a power outage. The flashing of the time of day can be stopped by pressing any button on the display.

Using a Raspberry Pi distance sensor (ultrasonic sensor HC-SR04)
For many (outdoor) projects a distance measurement is necessary or advantageous. These small modules are available starting at 1-2 bucks and can measure the distance up to 4-5 meters by ultrasound and are suprisingly accurate. This tutorial shows the connection and control. Hardware HC-SR04 Module (US / UK) Resistors: 330Ω and 470Ω (US / UK) Jumper

The solid-state ? timer requires constant power to operate the electronics. When a signal is received from the trigger circuit, the timing period is initiated. When the timing period has elapsed, the "contacts" change state. The contacts will remain in the activated state the entire time the trigger signal is present.

Jun 21, 2017F. At the end of the one minute time period, all of the TR contacts change position. The normally closed TR-2 contact connected in series with the motor starter coil opens and stops the operation of the motor. Normally open TR-3 contact closes and energizes solenoid coil C which permits liquid to begin draining from the tank.

A contactor is a large relay, usually used to switch current to an electric motor or another high-power load.; Large electric motors can be protected from overcurrent damage through the use of overload heaters and overload contacts the series-connected heaters get too hot from excessive current, the normally-closed overload contact will open, de-energizing the contactor

Synchronous Serial Interface - Wikipedia
Synchronous Serial Interface (SSI) is a widely used serial interface standard for industrial applications between a master (e.g. controller) and a slave (e.g. sensor). SSI is based on RS-422 standards and has a high protocol efficiency in addition to its implementation over various hardware platforms, making it very popular among sensor manufacturers.
