Product Features
- ESP8266 CP2102 NodeMCU LUA ESP-12E WIFI serial wireless module, built-in Micro-USB, with flash and reset switches, easy to program. Full I/O port and Wireless 802.11 supported, direct download no need to reset.
- Single-bus digital signal output, bidirectional serial data, digital output.can build thermometer electric circuit microcontroller, it can be used for robotics development kit, suit for engineer to make projects. Used for automatic control, weather stations, home appliances, humidity regulators, medical treatment, dehumidifiers, etc.
- The IR human sensor module working voltage: DC 2.7-12V; Static power consumption: <0.1mA;Sensing range: 100 degree cone angle, 3-5 m; (required depending on the lens) Working temperature: -20 to + 60 C.
- IR Pyroelectric Infrared sensor module based on passive body infrared technology digital intelligent automatic control products, high sensitivity, reliability, widely used in various types of automatic induction electrical equipment.
- PIR motion sensor detector module after the induction output is high, in the delay period, if the body in its induction range of activities, the output will remain high until the delay after the person to become Low level. (Ie, the sensing module automatically detects a delay period after each activity of the human body, and takes the last active time as the starting point for the delay time).
