Band Wireless

The Band Wireless model is designed to be used in facilities for reliable danger notification and haptic feedback in theme parks. It can be worn anywhere on the body, including the arms, legs, and torso. It incorporates the ESP32 wireless module and can communicate with Wi-Fi and other major wireless systems. The internal mechanism is almost identical to the Band model, with a built-in battery and wired input support, but audio output is omitted.

This product requires programming and is intended for developers. It is necessary to write firmware and voice data to Hapbeat using VSCode. If you need low latency (a few milliseconds) communication, we recommend using ESP-NOW, but you will need a separate transmitter using an ESP32 microcontroller (e.g., M5Stack).

This value includes the amount of rubber extension. In addition, the enclosure's width, 5.4 cm, is added.
In addition to this value, the width of the enclosure (4.4 cm) and the length of the thread ejected from the enclosure (2-3 cm per side) are also added.

The reference price is for the hardware only. We will support the introduction of general-purpose firmware provided by our company, but individual development costs are not included. We also offer system development services, so please get in touch with us if you are considering introducing the system to your facility.

When all LEDs, displays, vibration output, etc. are turned off until the drive signal is received
This is a reference based on continuously looping an EDM track with constant vibration at maximum volume on battery power. Continuous use while charging is possible, but charging may stop due to heat generation.
Measured values with Duo are common to all models.
Approximate: a few milliseconds with ESP-NOW, 1 second with Wi-Fi (via MQTT broker)
