Wireless Sensor Tags and Kumo Sensors monitor and record motion events, door/window open/close events, temperature/humidity/soil moisture and water leaks. They can send you emails, notify you on your phone when temperature or humidity is too low or too high, or each tagged item has been moved even only slightly, or when each door has been opened or closed. View graphs/data-logs of temperature, humidity, motion events at each wireless sensor anywhere with Internet. Attach to easy to lose items in your house and find them by beeping each tag from any browser or your phone. Out-of-range and back-in-range notification features come standard on all types of sensor tags. KumoApp Engine allows automation algorithms to be defined in Javascript to trigger Internet connected devices such as WeMo switches, Honeywell WiFi or Nest Thermostats and Phillips Hue upon events from sensors, schedules and geofences.

Internet of Things: Connecting physical world to the Internet

Fridge Temperature Monitoring:  High accuracy/resolution temperature/humidity sensor meets long range radio.

Temperature/Humidity/Light Sensor Tag: The simplest and most powerful solution for remote environment monitoring and automation

Angle Based: Ultra low power motion sensing technology

Temperature monitoring: Transmitting only when temperature is too high, too low, or back to normal saves battery life.

  • Temperature monitoring with battery life in mind.

    Wireless Sensor Tags are designed to maximize battery life. Since transmitting data over the air uses a lot more energy than reading from the internal temperature sensor, each Tag transmits only when temperature has become too high, too low or returned to normal range. To this end, each Tag has built-in algorithm with hysteresis (to prevent back-and-forth transmissions when temperature is at the boundary) to determine if one of these three events has occurred, and transmitting only then and if temperature monitoring is enabled.
    You can program the upper and lower temperature threshold and calibrate out temperature sensor offset from the "Temperature Sensor Options" (iOS, Web/Android).

  • Logging

    When "Auto-Ping" or "Update every..." is enabled for out-of-range notification, the tag appends the latest temperature sensor reading to the status information packet transmitted. Since the radio channel to the Tag Manager only needs to be made ready once, the additional battery drain is minimal.
    You can review historical temperature at each tag by tapping the "Temperature Stats" button in tag detail screen (iOS, Web/Android ). You can also download the entire captured raw data as one CSV file for custom processing.

Lost item finder: Single click/tap to keep tag beeping until found

  • Click/tap and go digging.

    Because each wireless sensor tag is so small, anybody can easily lose one. Tap the beep button in the iOS/Android/Web app, and the tag will keep beeping until it is picked up. All you need to do is track down the beeping sound and pick up the tag, and the beeping will stop automatically. See details: iOS or, Web/Android.
    Attach the tag to key chains, put inside your wallet, or strap to TV remote controls, and never waste time looking for these items again.

  • Customizable response delay and battery life.

    By using the Wireless Settings, you can change trade-off between battery life and range (slower data-rate results in longer range but worse battery life since it takes longer to transmit/receive), battery life and response time.
    For example, if it is something you only look for once a year, and want the battery to last several years, set it to "within 9 sec" response time, and "38.4kbps" data-rate, and battery life is estimated to be 85 month (about half of that when motion sensor is armed.) .

PIR KumoSensor: Smallest, professional grade infra-red motion + temperature + humidity sensor with 3x battery life

  • Smallest PIR sensor with professional grade reliability.

    Measuring only 1.1'' wide, almost its entire width is occupied by the lens of super reliable and sensitive Panasonic low power PIR sensor module. Our customers tell us this sensor has better sensitivity and less false alarm than any other PIR motion sensor they have tried.

  • 13-bit temperature and humidity sensor.

    PIR KumoSensor integrates high accuracy/resolution 13-bit temperature and humidity sensor, which allows you to cloud-record temperature and humidity data month after month, and get notified anywhere in the world when temperature or humidity is out of normal range. If you have a Honeywell WiFi or Nest thermostat, you can configure it track and regulate temperature at the sensor.

  • 3x battery life.

    Despite its small size, the wireless PIR KumoSensor includes the CR2450 battery which is enough to last for 3~4 years at the default settings. The industry leading low power consumption of the Panasonic PIR sensor module combined with "low power receive mode" in the radio makes the sensor draw less than 15μA average current with default setting.

Reed KumoSensor: Best for door/window, including sliding ones, + temperature + humidity + external probe connection and 3x battery.

Water/Moisture Sensor Tag: Detects water presence and measures moisture level.

  • Resistive water detection and capacitive moisture level sensor.

    This tag has a resistive sensor at its tip to detect water presence, and capacitive sensors across the exposed portion of the circuit board to measure dielectric constant of the surrounding soil or liquid (for water level).
    The moisture level is derived from measured capacitance after a two point calibration by user to define, what kind of condition is "0%" and what is "100%".
    The resistive water detector is immediate, while the moisture level measurement is taken and compared against adjustable thresholds at a user configured interval.

  • Longer battery life, water proof.

    By removing the piezo buzzer from the tag, we made room for a CR2450 battery which has 3x capacity than the battery used in our regular motion sensor tags. The circuit board, together with the battery have a water-proof coating. The battery will last for typically 3 to 4 years is not replaceable.

Out of range notification: Virtually no false alarm.

  • Get notified when each tag goes out of range and returns back in range.

    By setting "Auto-Ping" or "Update every...", each Tag is configured to transmit a status information back to the Tag Manager at a certain interval. Upon receiving such status information, Tag Manager transmits an acknowledgement response back to each Tag. When the Tag does not receive the acknowledgement, it repeats the status information transmission for many times before giving up and enter a hibernate mode.
    The system only decides that the tag is missing and send out notifications when it does not receive the status information by the estimated time plus the time needed for the retransmissions. Therefore, even when because of temporary interruption a single transmission is not successful, very reliably the system can detect if a Tag has gone out of range or gone missing.
    See how to receive out-of-range notification: iOS or, Web/Android.
