Sensors

Environment readings on the network.

Pythia TH1 temperature and humidity sensor with probe cable

TH1

TH1 Ethernet temperature and humidity sensor

The TH1 is a network temperature and humidity sensor with its own web page. Read it in a browser, poll it over HTTP or JSON, or let it push readings to a server on a schedule or when conditions leave a set range.

Web page shows temperature, humidity and min/max values
Simple HTTP outputs for temperature and humidity, plus a JSON output
Works with PRTG (HTTP Data Advanced sensor) and Zabbix
Pushes readings by HTTP GET at a set interval or when a value goes out of range, including to services like IFTTT
DHCP or static IP address, Fahrenheit or Celsius
Powered by USB-C, or over PoE with the optional PoE-to-USB-C adapter

Sensor	SHT30 sensor on a 1 m attached cable
Network	Ethernet, RJ45; DHCP or static IP
Outputs	Web page, HTTP (temperature, humidity), JSON
Push	HTTP GET at an interval or on out-of-range
Integrations	PRTG, Zabbix, IFTTT

I/O modules

Inputs and outputs for equipment with no network port.

Pythia CM03A 22 universal input module, front view with input labels

CM03A

CM03A 22 universal input module

The CM03A adds 22 universal inputs to a monitoring system or BMS. Each input can read a dry contact, a thermistor or a voltage signal, and the module reports them over Modbus or BACnet on Ethernet or RS-485.

Pythia CM04A 8 universal input, 14 output module, front view with input and output labels

CM04A

CM04A 8 input / 14 output module

The CM04A is a general-purpose input/output module for HVAC, lighting, temperature and other building automation points. It reads eight universal inputs and drives six relays and eight analog outputs, all over standard protocols.

8 universal inputs: 0–5 V, 0–10 V, 4–20 mA, 10K thermistor or dry contact
6 relay outputs and 8 analog outputs (0–10 VDC)
Speaks Modbus and BACnet: Modbus TCP and BACnet/IP on Ethernet, Modbus RTU and BACnet MS/TP on RS-485
Dual RS-485 pass-through ports for easy daisy-chaining
Static IP by default, DHCP available
DIN-rail mounting; power supply options available

Inputs	8 universal: 0–5 V, 0–10 V, 4–20 mA, 10K thermistor, dry contact
Relay outputs	6, rated 3 A @ 120 VAC
Analog outputs	8, 0–10 VDC
Ports	Ethernet; dual RS-485 pass-through
Protocols	Modbus TCP, Modbus RTU, BACnet/IP, BACnet MS/TP
Serial	9600–115200 baud
Power	15–24 VAC/DC ±10%, 50–60 Hz
Operating temperature	−30°C to 70°C (−22°F to 158°F)
Humidity	10–90% RH
Enclosure	IP31, DIN-rail

Use it where the system needs to switch or set something, not just read it: start a fan, open a damper, signal another system.

Leak detectors

Spot and rope detection for leak panels and BMS inputs.

LD1

LD1 point liquid detector

The LD1 detects conductive liquid at one spot, such as a CRAC drip pan or under a unit. Gold-plated probes set the trip height, and SPDT contacts wire straight into a leak panel, BMS or monitoring input.

Gold-plated probes, height adjustable 0 to 1.5 in
SPDT alarm contacts, field-selectable NO or NC
E/D jumper: energized or fail-safe de-energized output
Green power LED and red alarm LED, visible outside the enclosure
Weather-resistant NEMA 4 cast-aluminum enclosure, adjustable legs
11–27 VAC/VDC operation

Detects	Conductive liquids (water) at the probe
Supply	11–27 VAC @ 1.7 VA; 11–27 VDC @ 30 mA
Relay	SPDT, 1 A @ 24 VAC/VDC; 0.5 A @ 120 VAC
Probe	Gold-plated, adjustable 0 to 1.5 in
Enclosure	NEMA 4 cast aluminum, 1/2 in FNPT conduit

LD2 Series

LD2 sensing-rope liquid detector

The LD2 senses liquid anywhere along a rope run on the floor or under pipes. A separate Trouble relay tells you if the rope is unplugged, broken or cut, so a damaged rope never looks like a dry floor.

Detects liquid anywhere along a plenum-rated sensing rope
Independent SPDT Alarm and Trouble relays
Rope supervision: Trouble on unplug, break or cut
Trouble relay can be jumpered as a second Alarm relay
Multi-color status LED for power, alarm and trouble

Questions

Accessories questions, answered.

What accessories does Pythia offer?

The TH1 Ethernet temperature and humidity sensor, the CM03A and CM04A input/output modules, and the LD1 point and LD2 rope liquid detectors.

Which I/O module should I choose?

Choose the CM03A to read a lot of points (22 universal inputs, no outputs). Choose the CM04A when you also need to switch relays or set analog outputs.

Can the TH1 report to PRTG or Zabbix?

Yes. PRTG reads the TH1 JSON output with an HTTP Data Advanced sensor, and Zabbix reads it with an HTTP item. The TH1 can also push readings to a server by HTTP GET.

What is the difference between the LD1 and LD2?

The LD1 detects liquid at one spot, such as a drip pan. The LD2 detects liquid anywhere along a sensing rope, and its Trouble relay reports a cut, broken or unplugged rope.

Do the leak detectors work with the Remote Leak Detection Panel?

Yes. Both run on 11–27 VAC or VDC, so the panel can power them, and their SPDT contacts wire straight into the panel zones.
