NIST-Traceable Wi-Fi Temperature/Humidity Data Logger, Monitor, and Alarm System
T° Sentry TT-150 (and TT-200), Wi-Fi Sensor Data Transmitters
The T° Sentry TT-150 (shown below) is a battery operated, NIST-traceable wireless temperature/humidity transmitter and monitor/alarm for use with Wi-Fi systems. Standard systems cover a temperature range of -200 °C to +100 °C and 0% to 90% relative humidity in various selectable ranges. The units are housed in a wall-mount or free-standing enclosure.
Both systems also incorporate high and low temperature alarms with audible and visual alarm indication, temporary muting of the audible alarm for user-selectable periods (up to 120 minutes), optional UL listed plug-in power supply, and an optional dry contact input for refrigerator/freezer door monitoring, or data transmission activation.
T° Sentry TT-150 and TT-200 series systems are ideal for remote monitoring and logging of blood bank and hospital refrigerators and freezers, ULT freezer cold storage, and for walk-in environmental chambers.
Key Features:
- Continuous Wi-Fi transmission to ALERT Monitoring System data logging software.
- Portable, easily positioned modules.
- Battery operated (uses three, 1.5V lithium AA batteries, ~1-yr. battery life).
- -200 °C to +100 °C with variable ranges and probe types.
- Simultaneous temperature/humidity sensors available.
- Easy-to-read LCD display, 1 degree or 0.1 degree, °C or °F, %RH.
- Adjustable high/low alert condition settings and alarm delay period.
- Audible and visual alarms.
- Selectable audible alarm mute periods.
- Dry contact input for refrigerator or freezer door monitoring and/or Wi-Fi transmission activation.
- Optional SPDT relay contact output with adjustable relay delay period.
- Passcode protected setpoints.
Available Options:
• TT-150 (-100 °C to +100 °C): 100-Ohm RTD in
4" stainless steel sheath with 10-foot lead.
• TT-150-RHT (for room monitoring only (no probe): -40 °C to
+125 °C, 0% to 95% relative humidity (%RH).
• TT-200 (-200 °C to +50 °C): 100-Ohm cryoRTD with custom
stainless steel sheath and 10-foot lead.
• °C or °F temperature display.
• 3-minute sampling rate. Other rates available by request
(more frequent sampling reduces battery life).

Wi-Fi Transmission to the T° Sentry ALERT Monitoring Network Data Logging System
The T° Sentry TT-150 (and TT-200) temperature and humidity transmitters communicate via Wi-Fi to our T° Sentry ALERT Monitoring System data logging SQL database software. Wi-Fi transmission is via a standard UDP/IP protocol every 3 minutes, so the data is also available to other logging systems upon request. Consult Hampshire Controls for all available options and configurations.
Advanced users can interface directly with the SQL database and/or use in-house or 3rd-party tools to visualize/analyze data and/or to printout data for your needs.
T° Sentry ALERT Monitoring System Data Logging Software Features:
- Data logging for temperature and other physical parameters (RH%, [CO2], etc.), event logging, and alarm condition notifications.
- Independent sensor channel configuration and monitoring.
- Real-time data visualization in a variety of formats for single or multiple sensors.
- Interactive floor plans showing sensor locations and real-time sensor status.
- Email server settings, including contact groups and notification schedules.
- Email and/or SMS text alerts for system startup, shutdown, power, login, communication failures, sensor alarm, and sensor power conditions.
- Generation and distribution of reports at preferred frequencies with sensor readings, statistics, and logged sensor and system events.
- Password protected authentication for restricted users (guests), limited users, and advanced users (administrators).
- Automated SQL database backup.
- Remote access through any modern web browser.
