A module with a sensor used to measure the activity of the heart. It allows you to strengthen and extract the heartbeat signals from biomedical electrodes. It has an analogue output and a heartbeat indicator (LED). SparkFun SEN-12650

A set of test leads 2x4 (4 signal and 4 GND) with a length of 23cm and 22AWG intended for logic analyzers Saleae.

This disc load cell (sometimes called a strain gauge) can translate up to a whopping 200kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and proportional of, the strain (e.g. pressure or force) applied to the disc. SEN-13332

Module with 5V relay and timer. It allows the implementation of delayed switching on or off of the circuit with adjustable time in the range from 1 s to 100 s and from 1 s to 15 min.

Module with a 12 V relay and a timer. It allows you to turn the device on and off cyclically at a specified time using potentiometers. It can also operate in single trigger mode, which allows the device to be turned on after a signal has been applied for a specified period of time. The operating time can be adjusted from 1 s to 100 s or from 1 s to 15 min
