Simply point the sensor towards what you want to measure and it will detect the temperature by absorbing IR waves emitted
5V DC Relay (Songle) is high quality power relay
Non-inverting digital inputs are TTL and CMOS compatible
along withthe ability to drive 10 LS-TTL loads at LS type speeds
Solid State Relay Module (1 Channel- 5V) HC 05 Simply point the sensor towardsIntroduction : This module is capable of switching AC voltages between 100 and 240V at up to a 2A current. The module can be controlled from a 5V Solid state relays, have several advantages over mechanical relays such as It has a longer life, with a much higher turn on off speed and no noise. It also has better resistance to vibration and mechanical shock and better moisture proof performance. It can be switched by a much lower voltage and at a much
