    Analog illumination sensor with a phototransistor whose spectral sensitivity is close to the human eye (peak at 570 nm). Connects to the D105 analog input, powered with 5 V from the D105, output 0…5 V. Lux values are obtained after a simple two-point calibration.

  • Product description

    Light sensor | 570 nm | ±60° | analog 0…5 V | for D105 pulse analyzer | smart-MAIC | TEMT6000

    The TEMT6000 is an analog light sensor with a silicon phototransistor whose sensitivity is adapted to the human eye. It connects to the analog input of the smart-MAIC D105 pulse analyzer and outputs a voltage proportional to illumination.

    Key point:
    Measuring illumination lets you automate what is often done manually or with a timer: switching on outdoor, stairwell or shop window lighting only when it really gets dark. The D105 receives the sensor voltage, and in the cloud it can be converted into lux using two reference values. The sensor is powered from the D105, so no separate unit is needed.

    Connection to D105 and integration

    • Analog input (terminal 5) – The sensor signal pin connects to D105 terminal 5 (ADC). The 0…5 V output does not exceed the D105 analog input limit (0.1–18 V DC).
    • Power (terminals 6 and 1) – VCC – terminal 6 (+5 V from the D105), GND – terminal 1. No separate power supply is needed.
    • Calibration and data – The D105 shows the voltage (ADC). For lux, measure two reference values with a lux meter or phone app and enter the formula in the cloud dashboard. Data is available via API and MQTT.

    How it works

    The sensor is fixed where light needs to be assessed – at a window, outdoors in a protective cover or under a luminaire – and connected to D105 terminals 6, 5 and 1 with three wires.

    The phototransistor passes a current proportional to incident light, and the module converts it into a 0…5 V voltage. The D105 measures this voltage via its analog input.

    In the cloud you see the illumination curve (in volts or, after calibration, in lux) and can set the D105 relay to switch on at dusk or a notification if lights are on at the wrong time.

    Why choose the TEMT6000?
    It is the cheapest way to give the D105 “eyes”: illumination history, day/night detection and lighting control without a separate twilight switch. Its sensitivity is close to the human eye, so the reading matches how people perceive light.

    Key functions

    • Sensitivity like the human eye – the reading matches visible light.
    • Wide ±60° angle – assesses general illumination, not a narrow spot.
    • Powered from the D105 – no separate unit.
    • Lighting control – the D105 relay switches lighting on at dusk.
    • Illumination history – you see when and how much light there was.
    • Calibration to lux – a simple two-point formula.

    How does it differ from similar products?

    • D105 Solar – Measures solar irradiance 0…2000 W/m² via RS485 and needs 12–24 V DC; suited for energy assessment, the TEMT6000 for illumination.
    • G1/4 / mH2O / pH / TDS – Also connect to the analog input; the D105 has one such input, so they cannot be connected together with the TEMT6000.
    • DHT22 – Measures temperature and humidity via 1-Wire; it does not compete with the TEMT6000 for an input and can work alongside it.

    Where is it used?

    • Outdoor and yard lighting control
    • Stairwells and corridors
    • Shop windows and advertising signs
    • Greenhouses – light level monitoring
    • Offices and warehouses – lighting control
    • Animal housing – day/night regime
    • Home automation

    Use by need

    For apartment building managers.
    Stairwell or yard lights switch on only after dark – no timer adjustment every season.
    For shop owners.
    Window or sign lighting follows real daylight, and the history shows when it was on.
    For greenhouse growers.
    A light level history – easier to decide when supplementary lighting is needed.

    Practical use

    If yard lights are currently controlled by a timer and switch on too early or too late, connect the TEMT6000 to the D105 analog input and the D105 relay to the lighting contactor coil. Then set a threshold below which the relay switches on, and the lights will be on only when it actually gets dark.

    Pros

    • Sensitivity close to the human eye
    • Wide ±60° sensitivity angle
    • 5 V power from the D105, no extra unit
    • 0…5 V output suits the D105 analog input
    • Operating temperature −40…+85 °C
    • Simple calibration to lux

    Cons / limitations

    • Occupies the only D105 analog input – cannot be combined with G1/4, mH2O, pH or TDS sensors.
    • Shows voltage; lux requires calibration by the user – it is not a certified lux meter.
    • The D105 analog input measures from 0.1 V, so very low illumination may not be resolved.
    • For solar energy assessment (W/m²) use the D105 Solar, not the TEMT6000.

    Safety and installation notes

    • Connect the sensor only with the D105 power switched off.
    • Follow the wiring: VCC – terminal 6, signal – 5, GND – 1.
    • The D105 relay load is < 50 W – control larger lighting via a contactor.
    • Outdoors, mount in a transparent protective cover and protect from moisture and dirt.
    • Do not aim the sensor at the controlled luminaires – their light will distort the measurement.

    Quick selection guide

    ±60°
    0…5 V
    5 V from the D105
    Suitable when you need:
    • lighting control based on daylight
    • an illumination level history
    • day/night detection for automation
    Check before use:
    • that the D105 analog input is free
    • that the controlled load does not exceed 50 W (otherwise use a contactor)
    • that you have a lux meter or app for calibration
    Important reminder: The TEMT6000 works only with the D105 (not with D101 or D103), does not measure solar energy (W/m²) and without calibration shows voltage, not lux.

    FAQ

    Which D105 input does the sensor connect to?

    Only up to 50 W; for a larger load use a contactor.
    Is it suitable for measuring solar irradiance?
    No, the D105 Solar is intended for solar irradiance (W/m²).
