Industrial Grade Wireless Temperature Sensor – 6 Sensor Synapsense Replacement

This wireless sensor node replaces the discontinued Synapsense wireless temperature sensor module.  The Leap sensor node has a connector that connects to existing Snapsense temperature sensor wiring harnesses.

A Leap wireless gateway and Leap software are required.  Data may be passed to other software using the web-API or Modubs.

Convert your discontinued Synapsense monitoring system to the latest technology.


Part of the breakthrough Leap Sensors® system.


Leap Sensors are specially designed to easily adapt to your specific needs. If this isn’t exactly what you need, please contact us.

Wireless Temperature Sensor Specifications

Temperature Sensor Specification

Connects to Synapsense temperature sensors using a cable from the Leap Sensor with mating connector.

See the technical specification for the temperature sensor on the NCTDP datasheet.

Leap Wireless Sensor Transceiver Node Specifications

  • Transmission distance to a gateway – typically 200 feet in open air. The sensor transmitter antenna is on the circuit board.
  • 2-way communication with the sensor through the user interface:
    • Name the sensor, set sensor sampling time interval, set wireless transmit time interval, over-the-air firmware updates.
    • Gateways send an acknowledgment to the sensor that the data was received for high reliability.
  • Sensor data logging – When sensors do not receive an acknowledgment from the gateway that the radio transmission was received, the Leap Sensor will store the time-stamped data on-board until the gateway connection is established.
  • Reliable industrial over-the-air radio communication
    • Industry-standard 802.15.4 with Direct Sequence Spread Spectrum (DSSS).
    • Gateway “hand-shake” acknowledgments of successful transmission and sensor data logging for extra reliability.
  • Over-the-air protocol – Standard and established 6LoPan and Thread.
  • Data security – AES encryption.  Standard and established TLS security.
  • FCC certified.
  • Battery – 2 user-replaceable high-output 1.5V AA batteries.

Leap Wireless Sensors Gateway (Receiver) and User Interface Software

  • See the Leap Sensors gateway page and the Leap Sensors User Interface options page for more detailed information.
  • Leap Sensors wirelessly transmit data to a gateway*.
    • Gateway can support over 250 sensors that are in range. (Additional gateways can extend sensor coverage.)
    • The gateway then passes the data to the Leap user interface software. The user interface software may be hosted on the gateway (and connected to a PC with a USB cable), on the password-protected Leap Sensors Cloud web site, or an on-site server.
  • User interface supports: logging-in, set user rights, view sensor data, set email and text alerts (cloud version), graph sensor data, download data to excel, add or subtract sensors, update firmware, and other functions.

Data Passing to Other Software

Data from the Leap system may be passed to other software using the web-API, the Modbus interface, or DNP3 interface.
