O cenário
Design a low-power thermostat using an NTC thermistor and 555 timer to control a heater with hysteresis.
O que há neste desenho
Entenda as decisões por trás dele.
01
Used SPICE-style netlist mode for clean representation
02
NTC in voltage divider with fixed resistor for threshold, hysteresis resistor from 555 output to trigger input
03
555 timer configured as comparator with Schmitt trigger
04
Transistor driver and relay for load control
05
Flyback diode across relay coil for protection
When a simple, cost-effective temperature controller with adjustable hysteresis is needed.
